Here is an Excellent Article on algae (including pictures!), types, causes, control measures.

I set up an aquarium 5 gallon aquarium in my son's room, and we're looking for suggestions on what to put in it. A betta fish is the most obvious choice but we're open to other suggestions.

Idk if the pic is good enough, but i think he’s a male?

Howdy everyone! I've noticed several critters living in my substrate, the normal thin noodle worm, the little skittering white bugs, and recently a small shiny white worm (like ball point pen tip small, but chunky like a slug). It looks like a planeria, but super tiny, super white, and its insides (i think) are all white. Did an exploratory down there with long tweezers, it tried to run.... and the booger is to small to photograph. Any advice and tips?

This was noticed in my planted tank with endlers and cherry shrimp. So I am worried...

ive been really trying not to touch my tank since i put some of that beneficial crap in my filter to help it cycle, but after repeated testing my PH, KH, and GH just wont stop rising/wont go down, theyre all the highest they can possibly be on my tests. my cities water isnt great but i dont really have all that much distilled water right now (only about two jugs of it on me) what do i do to help with this?? is this deadly? should i be worried?

(a little bit of an unrelated question as well, but i also got a small reading of nitrate finally, ive also got a little bit of algae growth. should i do a water change or let it bake? ive got some java ferns and one betta in right now. would have loved to do a fishless but due to some complications i needed to add him in only after about four days of setting it up)

Hi everyone!

I’m new to this hobby, and want to do everything right. I’ve been researching like crazy, and even though I’m sure I’ve done everything I need to do, I’m so anxious for my fish.

I’m scared I’ll kill them because I’m irresponsible. Even though I’ve been doing my research, and doing everything right.

Tank is set up, and cycled. 10 Gallon. Over the course of this week I’ve added 3 guppies, 2 platy’s, and one oto catfish. I was super careful during fish selection, as I know these are two live bearing breeds, so I have an all male tank. So far, everyone seems healthy and happy, and seems to be getting along.

I test my water parameters daily, and today they’ll receive their first 25% water change with a gravel clean, because the ammonia is a bit high with the additions. Somewhere between .25 - .5

So here are my questions. And if anyone has the time to stop and answer and give me advice, I’d greatly appreciate it.

How often should your filter be changed?

How often should you actually do a water change? Answers seem to be different everywhere I look.

When I do the water change, should I treat my new water in the bucket before putting it in the tank? How do I get it up to temperature? And how much treatment should I use? Enough for the whole tank, or just enough for whats in the bucket?

My tank is not planted, but I was considering adding some top floating plants. Can I do this without it being planted? If so, recommendations for plants?

Did I overstock my tank?

I have my bubbler on full force. Should I put the valve on and adjust it? The fish seem to enjoy playing in the bubbles.

And, lastly, any other advice you have would be greatly appreciated. I want to know anything and everything to give my tank the best chance of thriving.

I've dealt with this before, not my first rodeo, but never this horrid. I've lost 3 fish including a male betta and a sucker fish, and molly (just bought 2 day prior to noticeable signs. I had 3 Molly's inhabitants in tank but noticed 2 males to 1 female. And it housed my daughters betta that died (hence why I add a new one to the tank). I've done everything I possibly can to raising temps 85°F, adding in ick prevention/cure, aquarium salt, sadly there are 4 left in the tank. 2 are seem yo having major issues with the slime coating it's shedding and almost looks like fungal floating around. I know doing too much can stress them out, too little will have worse effects! *** should I keep the uv light off or does it help kill off infection/infestation? Any other suggestions that I could do/try greatly helps thanks

I thought it would be interesting to know when everybody turns on and off their lights for there aquarium.

For example my lights are set to come on at 11:15 am and shut off at 7:15pm (8 hours of light) it turns on at this time because that gives me the most viewing time throughout the day.

This is a temperory tub for my baby flowerhorn , Tyrone . He might have to stay here till he grows to a decent size to be put in a single tank . There is a sponge filter and some algae , is that enough for this tub.

As you can see, there is some white "stuff" on my hardscape (spiderwood). It has been there for, I think, 3 days. I tried to remove it manually, but It didn't quite work so I gave up.

Can anybody tell me what this is and if this is harmful?

I am currently cycling my tank and there are no animals, besides the few snails that where on the plants that I put in there yesterday...

I think this is a biofilm of dead bacteria and shouldn't be harmful, but I'm not sure.

Please help!

I have 4 Platy fry that are now 1cm in size. Don't want more fish population in the tank.

What can I do? Any suggestions?

With this method you can stop unnecessarily caging pregnant guppies in little breeding boxes which stresses them like hell.

I make this post because I see this a lot here that people put fish in tiny breeding boxes.

New born fry will use it to rescue themselves from getting eaten by bigger fish.

If they hide inside you can catch them easily.

Hi!!! I am at a total loss, i have a green lantern platy that I got when she was pregnant (unknowingly)- her and the 8 babies have been separated, mom is in a 10 gallon and loving life. However, yesterday I noticed two (maybe three) babies!!! she’s been by herself since I got her, no tank mates. Has anyone else experienced this, are live bearings able to make babies by themselves typically, is she a special case? or were these one delayed? her last litter was roughly one month ago Mom picture included, her name is Miss Opal but in light of recent events I am considering changing her name to Miss Mary

Hier kunnen nog geen vissen ofz bij toch? En weet iemand wat ik zou kunnen doen om ze goed te krijgen?

Water verversen?

Bedankt voor de hulp 🙏

Hi there, I don’t know what to do about my guppy fry. I’ve had two separate rounds of fry where I separated the fry from my big tank and added them to a 3 gallon tank. The first time I had aquarium rocks and plants, a water heater, a filter, and I filled the tank with water from my big tank so I had cycled water, two of the guppies seemed to have burrowed into the rocks and couldn’t get out an the third mysteriously died overnight.

Fast forward to yesterday, I removed 4 guppy fry from my big tank. I removed the rocks from my 3 gallon tank, left the plants, the tank heater, the filter, and I refilled the tank with my aquarium water again. They looked fine last night but then I woke up this morning and all of them had passed. I don’t know what to do differently for them to survive.

Hello, I've got a 29 gallon tank that's a low tech planted tank. I have driftwood and some rock currently cycling and wanted your thoughts on additions, substitutions or subtractions from my current plan.

5-6 Marbled Hatchet fish (I have a good top cover for the tank

7 - 9 Cherry Barbs

5 - 7 Kuhli Loaches

(I'm assuming a centerpiece like a Pearl Gourami would be too much with everything else)

Some Nerites for algae

Substrate is coarse sand with Monte Carlo

Some leafy mid level plants (still deciding on what) possibly Java fern anchored to the driftwood and rocks.

An Amazon sword

• Fluval 107 canister
• Fluval Aquasky (18w / 24-36") light
• Air bubbler disk cause why not?

Also interested in some type of floater but I'm concerned the current may be too high even with the spray bar (I can always reduce output but want to make sure it's cycling enough for the bio load). The lid is glass so I may have humidity issues. Our inside air is very dry so that's why I'm opting for a glass top vs a screen, hopefully to cut down on top offs. I'm on treated city well water and have a softener but hopefully will be installing a RODI soon as I have the basics to start assembling a reef tank in the future.

I'm guessing no Neo Shrimp due to the fish choices, I've had tanks in the past but never these species before. Probably just going to take 2 of my 10's and breed some Neos, then if anything culls can be added in.

Pros and cons of buying Two 350 EHEIM Classics vs one 600 EHEIM Classic for a 75g tank?

It will likely stock it with smaller schooling fish and shrimp. Almost like a big nano tank with aquascape.

At first I was going to start with one 350 and add another in the future if needed. I also have a bunch of fans I could add to increase circulation if required.

Thanks!

Ok, so months ago we upgraded our 10 gallon to a 20 long. We have a 40 breeder. We are using the 10 as a quarantine tank. When I first filled the 10 gallon weeks ago, I filled it with water but I didn't treat it with prime first. I know, I know. Down went a lot of good bacteria.

Fast forward to now. We have another batch of fish we are quarantining. We have been treating all fish with levamisole, waiting a week and redosing. Water changes to help with any higher ammonia or nitrite. So far, it's been fine. The nitrites shot up. Did four water changes in two days. Nitrites are still at 1 or slightly higher.

Should we continue doing the water changes, trying to keep the nitrites as low as we can until we can do a second dose of levamisole? Or would it be better to just transfer them to the main tank? All the fish look great and seem happy (slightly stressed from nitrites I would guess).
