I have a 40 breeder that was for Hillstream Loaches, but most of them have been moved to a different tank for breeding. There are still a few in there and some Cory's. I have been looking for a single large centerpiece fish for this tank since I did that and am currently considering a Vampire Shrimp.

The key things I'm seeing is flow and food, I think food is covered since without UV this tank ends up getting a fair bit of algae in the water, but also for the Hillstream Loaches it has a pretty well established ecosystem with biofilm and all. Either way I'll probably get some food for it to make sure it's good.

The other thing I'm trying to see about is flow. Before when it was a Hillstream tank it had a big 110 HOB filter on full (on a 40 gallon) and a powerhead, now it just has that big filter. There is enough flow that little particles, plants and free-floating snails get wisked around, but not too high that the Cory's can just chill in one spot on the bottom. So how much flow do they need? Hillstream powerful flow or just enough that the tank is well circulated?

Currently has 2 neos, 1 ghost and a tiger nerite. The ghost is on her last leg and once she’s gone I’d like to add more neos. What’s the ideal amount for my size tank, including the 2 neos and my snail? Thank you.

She was like that this morning still moves occasionally but mostly still. Water parameters are all fine except KH which is on the low side - will fix that today. All other shrimp are fine, no unusual behavior.

They were moved to this new tank a few days ago after it finished cycling. Same water source.

Does anyone here have recommendations for filters for 10-20 gallon tanks that won't suck up shrimp? because there are so many filter options and I am overwhelmed by it

any tips? I only have shrimp in here

(enjoy this picture of my alive shrimp) I got shrimp less than a week ago. They have all looked healthy and have thrived, other than about 4 just dropping dead (3 juvenile 1 adult). I thought this started when my (new) corydora dropped dead and i assumed the deceased shrimp had eaten it and somehow gotten infected, but now my last black neon tetra (3 years old, rest died of old age) has passed. This tells me that either it is a nasty coincidence and her time has come, or that there is some invisible disease going around my tank. What could possibly be killing my animals if none of the parameters are off and none look distressed or outwardly diseased?

note: My tank is almost 5 years old. It (now) has <20 shrimp, 1 corydora, and 1 ember tetra (most tank mates have died and i am waiting for shrimp population to increase before adding my pearl danio school back). I already use aquarium salt in my tank (2 Tbs for the 10 gallon) to promote health. I have also done two 10% water changes since the first death (thinking it was an ammonia spike). My (very sensitive) plants are still thriving.

Every caridina breeding setup I’ve seen use aquasoil but all the aquasoil I’ve use from Ada to uns to stratum, they all buffer the water PH to high 6s, which is what they designed to do. I’ve been keeping caridina in tank with aquasoil and they do fine but they don’t breed and the only reason I could think of is the ph not low enough. But doesn’t matter what I do to lower the ph, ro water with ph6, tannins, the soil just bring it back up to the high 6s. I’ve been thinking since my RO is about ph6 I should just take out the soil and use something inert instead but I still don’t understand how people do it aquasoil consider some caridina was recommended to be in ph as low as 5.5

Managed to slowly building my shrimp community after trial and error. At first I do have continuous shrimp rip later they settle down and have babies and no RIP shrimp anymore for one month or so. Suddenly just now I saw one rip it don’t seem an old shrimp as it is mid size. The rest all ok. I feel curious is normally are those big shrimp rip due to aging now this is not old shrimp , quite young as it is middle size. I guess is random rip ? Is common ?

Setting my new tank for my shrimps and sheimplets but the water changes to light green immediately after pouring water within minutes Any suggestions??

I pushed it back in

(Jk, she fled as soon as I got close)

I have a tank fully cycled, walstad that started with 12 monos and 10 bloody Mary’s. We lost 2 to the change and 2 to molting issues. I then bought more bloody mary’s and have lost more, again to molting issues. Now even one of the monos is on its back struggling.

I cant seem to figure out whats causing the failures, Ive measured ammonia, KH, GH, nitrates, copper, and all the values seem well within range! Im loosing many shrimp and in a short period as well, at a rate of 1 a day almost for the last month, (its a newish tank) and really just wanted a nice bloody mary tank. Any advice?

I have a very small internal filter that I want to add to a 6 gallon shrimp tank. I have a sponge filter but it takes up far too much space so is there something I could do to make sure no shrimp can get into the internal filter?
