I currently have a 10 to 13 in. electric catfish swimming around in a 56 cube that is 30 by 18 by 24 inches. He is still growing and I have no idea where or how to house this fish once he outgrows this tank. I bought a 300 gallon,but the weight proved to be to much for my house and caused damage that had to be repaired. Anyone have any ideas on how I can keep this fish? Also this is the first time I have posted a thread, so I hope this is the right section.
