Stocking for a 55

    Hi everyone,

    Im getting a 55 gallon soon and was wondering a tank this size is big enough for a small school of boesemani rainbows?

    IME large active fish like that need an 18 inch wide tank to maneuver. An 18 inch tank provides 50% more of a footprint. You might be able to keep a small (4?) school, in a 48x12, but I think the fish need at least a 48x18 for a small school. Bigger for a bigger school.
