Officially, the tank is set up, it actually just finished cycling yesterday. I've decided to hold off, however until I figured out EXACTLY what I was going to do with it. What I'm hearing here is essentially what I'm hearing online. Some people say that 30 gallons is plenty for a dwarf, in fact most reputable sites I've seen have 30 gallons as the recommended size for them (by reputable I mean sites that aren't describing AND selling the fish) but some people say that even the smallest lion shouldn't be in anything smaller than a 55, which is what alot of sites recommend for the volitans. Is it possible that these discrepancies are because of mis-identification? Considering that a dwarf zebra gets to be 6-8" long (and most sites say the average is closer to 6"), it seems unlikely that a fish that is only a sixth of the length of its tank would outgrow the tank. As far as wastes go, I will do what I can to take care of that, but size-wise, it seems unlikely that it would outgrow the 30, especially the dwarf fuzzy mentioned earlier that outgrew its 30, considering they're even smaller.
