Re: Dead fish in a clean tank.

The Pseodochromis apparently has velvet. Now the Flame angel has fin rot,
all from one freakin fish (now deceased). It's going to be about impossible
to carch these guys. If I blast the tank with erythromycin, would the whole
ammonia-nitrite-nitrate cycle start again? (80 gallons, 70 lbs live rock, 4
inches of substrate)

Meanwhile, I'll check the LFS's for a trap or something.
