All tanks come with fish, filters (55 and 75 have canister filters), lights, heaters, food, etc. We are moving and cannot take them with us. You must move them yourself and come with the necessary things to transport fish. All tanks are freshwater and have been running a minimum of 6 months to 2.5 years. Asking $400 for the 75, $250 for the 55 with three large fancy goldfish, and $75 for the 10 with pea puffers. OBO
