No more CL tanks of any-kind for me, I'm pretty satisfied with the 6 tanks I have. Unless I find a CL tank 400 gallons or above or I build my own plywood/glass front tank. In fact all my projects are on hold for the foreseeable future. I consider myself blessed to even maintain what I have now, but having got the hang of keeping fish successfully its got to be one of the least demanding pets to maintain. Much easier then say a dog or pet bird, cats are a close second.
