I currently have a planted 75 gallon tank and at first I was planning on getting a Spotted Congo Puffer, but seeing such a steep price is hard to swallow. How long could I keep a fahaka in my 75 until I have to upgrade into presumably a 125 at minimum? Is there any precautions for compatible tank mates, I already had a SAE, L-Catfish, and 1 angle would those be ok? If not I could move them to a different tank. Would fish like rainbows work? If not what other fish could I keep in this set up. Of course I will further research the fish but I wanted to hear from someone directly about tank size and tank mates. I really want a Puffer of some sort and I'm really drawn to a Spotted Congo but with the aproxx. 200 dollars I spend on it that could go towards another tank for a fahaka. Thanks!
