I have a 29 gallon tank (30"x12" foot print) and I've set my heart on keeping and breeding Steatocranus casuarii. I'd like to set it up as a Zaire river bed biotope, ideally with African glass catfish. I understand though that both the S. casuarii and glass catfish use the bottom of the tank, and it is a small tank... Also, I've tested my water chemistry, and I was encouraged by 0 ammonia, nitrites and nitrates, but dismayed by an 8.2 pH. I believe that this was caused by my purchase of African cichlid gravel (Whaddaya MEAN there's different water systems in Africa?!). I could replace the gravel and start my cycle over again, if that high a pH would significantly stress my fish, but if it wouldn't bother them I would just assume leave it. Thoughts, comments and etc. are appreciated!
