HI all, I have several tanks, but I have one that seems like all the fish stay stressed, but few are still breeding. I have 2 bristlenose plecos, the females are seem to stay pale. I have 6 black skirted tetra's that seem ok, but skitish, and stays to one side of the tank. I have 6-8 cory cats that hide most of the time, the dorsal fin seems to always be laying down. I also have 2 opaline goramis and 1 lone Cherry Barb
(all the others have passed at different times over the past year.
As for the breeding , I've had 2 batches from the bristlenose, lost all of the last one to a nitrite spike (caused by me, I know what happened and have it fixed, dang zeolite) I have a baby cory from time to time.
I had a white sand bed, but I'm slowly changing it over to black gravel. I thought the darker gravel might make em feel better.
I change 5 gallons every week, tank is a long 30, with a whisper 30 and 40. A couple live plants and alot off moss on the driftwood. I have the standard lighting on way to long. I feed, flake, shrimp pellets, and algae waffers, and the occasional cucumber.
I'm just concerend cause all my fish seem to cower on one side of the tank towards the back.
Any idea's, thanks for the help.
