I have a 20 gallon long (30" long) that is fairly well planted with some driftwood and rock, and seems to have enough space for more than one territory for bottom dwellers. Could i safely add 2 pairs of rams (i've only seen blues locally but if i ran into bolivians i'd get those instead) to this setup (after the cycle completes and i confirm appropriate water parameters of course)? Is it one of those maybe, maybe not situations? Or absolutely out of the question?
