I have a 55 gallon display tank in my living room I'd really like to restock. The current inhabitants thrive in there and live peacefully. I have in the tank right now:
1 Angelfish (approx 6-7" tall)
6-7 danios (hard to count b/c they move so fast)
1 Upside down cat (possibly more, but I see him occasionally he's a very good hider)
3 Glo-lites
6-7 cory cats of different varieties
1 male platie
Obviously, the tank is somewhat understocked. I've had it set up approximately a year and 3 months. Ammonia and Nitrite are 0, Nitrate is approx 5.0, and ph is somewhere between 7.6-7.8 (hard to tell with the test kit, but that's what my tap water tests).
Like I said, the inhabitants seem to thrive, but when I add any new fish they seem to die pretty quickly. I've lost 3 angels, 3 platies, and 6 otos among other things. Usually they'll die within a day or two of adding them. I've heard otos can be hard to acclimate, but hadn't heard that about angels or platies.
I'd like to add 2-3 more angelfish, 3 female platies (to produce snacks for the angelfish), 3 more glo-lites and a handful of cory cats. Obviously, I wouldn't add these at once. Anyone have any ideas what's killing the new fish? When I add fish to my other two tanks (which have similar water parameters), I don't have this problem.
