Thanks Guys =) I'm just wondering if I need to plan for a big tank in the next few years or if the 40b or 75 will be sufficient.. I'm actually hoping for once this is one of the smaller species. So far he seems to be eating mainly blackworms I haven't noticed a dent in the minnows yet, If he leaves them alone I may swap them out for some platies or guppies to bring some color/action to the tank during the day. He's been extreamely active at night and extreamely recluse during the day ( as to be expected) Any suggestions for some colorful tank mates? The tank is upstairs in the living room so I'de like to have some movement during the day other then just a nice planted scape. most of what I had in the tank was fairly aggressive, and I haven't put my banjo catfish back in yet... do you think he'll leave them alone or be digging them up constantly like our dolphin did?
