For example, if I have a rainbow trout, then slowly change out the water until it become saltwater, can that make the trout transition into a steelhead? Or does it have to be a select certain amount of trout that can do it.

i recently got a discus fish because they’re so pretty! i have a black moor goldfish in another tank of mine that’s smaller and i was wondering if i could add him to my big tank with my discus fish, i’ve heard they’re quite friendly fish so i don’t see why they couldn’t live together, just want other’s opinions before i add him to the tank just in case anything happens to my discus bc he was expensive and my favourite fish i’ve ever had, i just want to keep him happy and healthy:)

It was raining heavily and this huge catfish was wriggling on the road. Do you know which catfish is this ? Location - Bangalore, India

I have 3 yellow labs (1 male 1 female and 1 is too small to tell. How can I encourage the male and female to breed?

As a fisherman seeing some of the guys here post their catches. Already dead and have absolutely no idea what fish they caught. It enrages tf out of me how some people go out to fish with no care to rules or regulations specific towards the no idea if the fish they caught is even legal. If they don’t even know what fish they caught how can you assume here in the (US) if it’s even a legal fish. Was it is season, was it oversize,undersize, do you know the limit on the fish. There has to be fishermen’s education or something like how we have hunters ed

hi guys. they fell out of my swimsuit after i was attacked by a school of them (PCB Florida). they are unfortunately dead, but i held a small candle lit vigil for them before flushing down the toilet.

thank you!

Pet co sold me these as dwarf catfish I just wanted to know if that is true because the lady there said she did not know anything about them.

Are Bonito fish big??

hello everyone, i’ve been playing to get a trio of golden wonder killifish in my 20 gallon tank and I just had a few questions to ask. I heard some people say they eat only live and frozen food but some people say flakes and pellets works too. Is a trio enough? 1 male 2 female. Can they live with pygmy corys or will they fit in their mouths. Bonus unrelated question, best way to set up a black background besides paint? I know its alot of questions but please help!!

My gf found this washed ashore I n Margate, NJ. Anyone know what it is?

I have 1 Panda cory (3 died) and have recently added 2 apistogramma pandurini. The apistos are aggressive toward the cory and keep chasing it whenever it gets close to them. If I added more panda corys will this help to reduce the bullying? I do not want to buy more Corys if the bullying won't stop. Please advise me. I have a 15g tank with rocks and driftwood. There is enough hiding spots.

I found this fish at work and no one seems to know what it is. They have a kind of green or reddish brown color on top and the sides are entirely silver. From above as well, the front of their faces, like around the mouth, looks almost transparent. When I shine a flashlight at them, they take on a green/blueish color with purple bellies
