So my spotted Bass is getting a larger tank. Going from 20 gal to 55 gal. I have searched the forum somewhat but I have a few questions. First off, I filled the new (used) tank with water to check for leaks. My next job is the transferring of the fish. I have read about cycling and what not but does a Spotted Bass need the same treatment as a delicate tropical fish? I plan on siphoning almost all 20 gallons of the existing tank into the new one and then filling the rest with filtered, treated water. I basically did this when I first caught the bass and he was fine. Also, what structure works best here (rocks, limbs, manufactured?) Next, I would love to put another fish or two in there. I want a crappie and maybe a bream or catfish. Any suggestions on what combinations work best here? Lastly, the newer tank I got didn't come with a lid or anything else. Is it possible to just buy that? I plan on using the old filtration system and adding a second one. Will that do the trick? It seems most of the topics in here are for a little less resilient fish. Am I right?
