Today when my wife came home we found three of our fish stuck to the intake of the filter and our clown pleco dead at the bottom of the tank. The three fish that were on the intake were purchased at the same time and the clown pleco was new (2 days). They were fine in the morning and our two striped raphaels and our everclear fish and other neon tetra were fine. She tested the water and all normal levels (7.0 pH, 0 for anomnia, nitrite, and 5.0 for nitrate). After about 1/2 hour, the other neon tetra was gasping for breath and dying. She looked up on the internet and it said something about it being oxygen deprivation so she did a PWC, but the neon tetra died. The cat fish and the everclear fish are still around, the catfish seem to be spirited and the everclear fish is hiding (she thinks it didn't eat).
We had purchased another clown pleco which died the very next day and one of the striped raphaels and the neon tetra one day. Then went back and got a new clown pleco and another striped raphael. Then later on bought the cave piece for the catfish who are quite shy.
Could it be oxygen deprivation, the amount of new fish bought or even the cave piece? We are very frustated, my wife doesn't want to give up the tank but I feel like we should. Any advice is appreciated.
Thanks.
