I have a 125 gallon aquarium held at a temp of 78 degrees with the following fish: 1 bala shark, 4 tiger barbs, 5 white clouds, 5 zebra danios, 3 lemon barbs, 2 placo's, and 2 upside down catfish. I have plants on the left side of the tank for hiding and a barrel on the right. In the middle I have a river scenery thingy that pumps air into the tank. The tank is over 3 months old, I have changed water and gravel cleaned several times. I just had my water checked as I do every week and all looks good to the experienced fish store person. The only thing we found abnormal is the ph. It appears to be high. Two nights ago I treated that with the correct chemical to bring the ph down.
My problem is: I used to have gourami's (4 to be axact, not all at the same time). I tried having 2 at a time. They eventually all dies the same exact way. They began swimming in fast circles and bumping into the walls. When they weren't doing that they would lay down somewhere in the tank till I tried arousing them and they began the bouncing around again. To move on, I assumed it was over until it began affecting other fish. I have lost a tiger barb to this, a bala shark to this, and 2 lemon barbs as well. I have tried to put salt in the water inside a bowl for stress and the water tests showed it had normal salt levels. I have put my arm in the tank to remove dead fish and to put in and remove some squash for my placo's.
I am confused! HELP!
