Im told he is about 5.5in long and the guy only wants 10 bucks. He is a rescue from some guy that had to go overseas for a year

They will be going into a 55G tank. I do need to get some PVC to make caves for them, but its already planted with rocks to hide under. I have only found the one raninus, a local rescue guy has a 5.5in specimen that was given to him.

Do you believe with a 55 I peacefully have the raninus and say 4 ...

I found a Batrochoglanis raninus (bumblebee jelly catfish) and im wondering if an african brown knife fish would be a suitable tank mate?
