I got the big tank off craigslist i know i have 3 HOB filters on it but i plan to get a large canister filter for it when i get the money also get one for the 26 gallon when i can.

Please tell me what you think they are both new and plan on trying to sell the iridescent shark when i can dont really like how much he/she eats.

I just added a plastic black backing that came with the big tank will eventually paint both of them. Wanted to get them set up to start cycle when I got them then relized how hard it would be to paint them till i drain them when ever i do that

Ill take some pics right now to show you the new setups give a little bit my son is hungery
