Thanks everyone! Gotta love how the tank went from a 20 to a 90 in less than a year lol. Hopefully I won't get the urge to upgrade again. Can't be much longer before the tininess of the fish and the hugeness of the tank gets to be absurd.
BTW, I tried coating an algae wafer like you mentioned earlier, and they're still eating it now without any of the coating... finally!
