Something more related to the last thread, would a pair of vaillanti gouramis work in a 25 gallon or slightly less sized aquarium? (It’s a Red Sea Max 130 which is 34 gallons but that includes a small sump that I don’t use.)
Sphaerichthys seem to be more of a schooling fish and also aggresive, which might mean one pair would be shy or aggresive. But it’s a more colorful fish that would probably attract more attention in a store if I bred them.
Maybe it would work fine to have a pair by itself in that sized tank.
