anybody know if there are smaller species of pickerel than the grass and redfin pickerel availible? i recently moved and broke down all but 2 of the 8 aquariums i had, and am in the process of taking down the others, however today i was looking at my 29g and picturing a jungle of driftwood and vals and was thinking that it would be a perfect grow out tank for a small esox. i've never kept pickerel before, and my experience with predatory fish has been limited to a Butis butis, Lepomis cyanellus, Ictalurus punctatus, a few puffer species, a couple gobies and a Hemibagrus wyckioides, so any tips would be helpful. how fast do they grow, how easily can they be weaned off of feeders(i'm planning to breed gambusia in the sump) what are their captive habits? i was looking at SACHS and saw that they had 1.5"~3" grass pickerels. is there other species of fish like pickerels that would be better?
