I've got a bunch of Tangerine Tigers. They're at least as hardy as Cherries in my tanks. Have them in everything from GH 5 to GH 14, pH ranging from 5.5 to 7.5. Kinda need to add to the bloodline, though.
This tank is three feet from where I spend most of the day, so I want something interesting. Am fortunate to have all kinds of shrimp on-hand, so that's not an issue. Just have to make a decision.
Directly beneath the tank is a 3gal with Snow Whites and beneath that, PRLs. Something different would be nice.
