I hear you on doing TT on one or two fish at a time. And I'd definitely do that, but when I put in orders from Blue Zoo or Live Aquaria, I always need to get groups of fish to make the shipping worthwhile... So unfortunately this is how it has to be done. I'll drop a dose of Prazipro in there and continue it through the TT process. Hoping for the best.
Has anyone else had bad experiences with Blue Zoo? The blenny was on sale and I wonder if perhaps he was the sickliest last fish from a group they were trying to get rid of. He really is ribbon thin. Perhaps internal parasites are at work too. In any case, I'm thinking I'll discontinue ordering from them. I've had at least one DOA or DAA (death after arrival within a few days) on every order I've placed from them. They're great about issuing credit, but come on...
