I've been reading obsessively about fish that may be appropriate for my tank when the fishless cycle completes. It is an extremely well filtered 20 gallon long, well planted with lots of cover and driftwood and little surface agitation. I'm planning a school of small fish with a centerpiece fish or pair that is larger. I was originally thinking of a m/f pair of dwarf gouramis, but females are next to impossible to get and the stock of males around here seems to be of dismal quality. So i was wondering if maybe a single male paradise fish would work. I know they are aggressive and couldn't be kept with anything very small or long finned, but maybe zebra danios would work? Any ideas?
