I know the pleco did't kill the cory since they were 1 day in the new tank, I just bought them. The pleco is too young to sex, and I put in about 3 wafers for my snail, kuhlis and the pleco and corys. I only have 2 corys now, and they are acting like normal fish and swimming midwater with the guppies, is this normal when there is not enough to school? I am getting 3 broze/green to put in since they are the same species and I heard they will school. So I will have 3 albino and 3 bronze.I had the same problem with a young male bristle nose. He would charge after the corries he they came out into the open. Easy fix, I moved him to a different tank and now he only charges after the younger BN and occasionally the female bettas but not nearly as bad as he did with the corydoras.
Your pleco is just being territorial. I cannot see a pleco actually going after another fish to kill/eat it unless it is starving. Pretty sure you other cory died from something else and the pleco was just cleaning up, as they often do. If you don't have another tank to move either the pleco or the corydoras to then try splitting up the wafer and putting the pieces in different areas so they all can get some.
I have the opposite problem, my tequila splitfins and limias constantly pester my plecos lol.I have 2 albino corys, I had 3 and was going to get more but one died. The pleco was eating the dead cory and I took the dead body out. now the pleco chases my corys trying to bite them, is this a problem. I just put algae wafers in and he attacks any cory that comes near his wafer.
I am getting new food soon, but the pleco eats algae and some wafersThe BN probably is hungry. Give it fresh vegs. And the Corys a more protein based food
it is a 10 gal, but there is a cave and he stays in the middle of a big sword plant a lot. He doesn't use the cave because I think the kuhlis took it over.How big is the tank? BNs can be surprisingly territorial if the space is small or if they don't have a little place to call their own
He died the day after I got him, but the tank has a filter full of sponge, and a lot of plants. I didn't do a water change over a 3 week vacation and everything was still at 0ppm, so water quality is not a factor. The pleco is pretty small, a bit bigger than the guppies, and I am getting a 29 soon and the cories and pleco will go there,maybe the kuhlis tooI didn't think to ask the tank size. No pleco should go in a 10gal and the corries need a larger tank as well.
With the loaches, corries, and pleco there are far too many bottom feeders in such a small tank, creating conflict for space. I think you need to upgrade to at least a 29gal for all those species of bottom feeders to live harmoniously.
If you have that many fish and are feeding 3 algae wafers every time, I am concerned about the water quality. Perhaps this is a contributing factor to the cory death.
If your parameters were 0 across the board, there’s part of your problem. Tank isn’t cycled.He died the day after I got him, but the tank has a filter full of sponge, and a lot of plants.

The tank is over a year old, I think it is cycled. I looked at the paper from Petco since it was done there, and there is 0 ammonia, 0 nitrite and 80 ppm nitrate. That was a month ago, and ive done a few water changes since so I don't know what it is at knowIf your parameters were 0 across the board, there’s part of your problem. Tank isn’t cycled.
Then it wasn’t all 0’s. but on the flip side, 80ppm is to high. You don’t really want it getting over 40. 20 is best.
I thought it was all 0s, I have done water changes though. I have also added a few more plants.Then it wasn’t all 0’s. but on the flip side, 80ppm is to high. You don’t really want it getting over 40. 20 is best.
If they’re both tiny, yes. But from what I’ve heard BN’s can be very territorial to their own kind and 30 gallon is not enough for two.
I also upgraded the filter from a really old tetra 10 gallon semI internal filter to a new HOB filled with sponge, and since then I have added a few new plants and the other ones have gotten a lot bigger.
