Hello!
We currently have a 75 gallon freshwater tank, which is well established. The tank currently has:
6 neonrainbowfish (3 females, 3 males)
2 bala sharks
1 pleco
We were considering some pictus catfish, but we weren't sure if they would be compatible with the fish listed. The tank is in great condition, although the
pH is 6.2, a little low. Some sites for the pictus state that the fish can handle from 5.8-6.8, while others say 6.5-7.5. Any verdict on the pH??
One more thing: how many pictus can fit happily and safely into the tank
Thank you!!! Sorry to ask so much at once,

but I'm curious!
Thanks again!
