Depends on the pim, striped will get a foot, spotted pim only USUALLY reach 5" like any other animal a few can and will exceed the standard hence your 7". But i agree no-go and they need to be kept in groups of 5 or more. wikipedia says the striped raphael gets 8", again you may have an exception (this is how we developed the world record system). not my type of fish anyways. i was thinking IDK really yet perhaps a synodontis or... no ideapictus cats get 7" and rapheal cats get 8-9" i couldn't imagine putting my pictus cat in a 10 wayy too small
It depends. the requirements are not set in stone, if you know of some kind of off-the-charts beautiful cichlids, loach, or something tell me! If its a single specimen tank no bigger than 6". If its a pair, no more than 4". It could be a community planted tank, It could be dwarf puffers. It could be nothing but plants. It could be shrimps only. IDK, really.how many inches were you thinking?
