i would say a 75 in the min unless you buy the rhom at like 16inch then the min is a 180
if you buy a small rhom under 12inch a 75 is fine as most rhoms wil lnever reach 18inches unless captured from the wild at that size
the types of rhoms depend on collection point
like xingu rhom (from rio xingu in brazil), peruvian rhom (most commen form peru), venezalen rhom (also called "vinny rhom"), guyana rhom, black blue and gold diamond rhoms
go to www.aquascapeonline.com and there is pics off most of the rhoms i said
