Hey guys! Posted here since its an emergency to me and the seahorse board is kinda slow. I bought 2 hand raised juvenilles (Romeo and Mercutio) from DNA about 3 almost 4 weeks ago and they are healthy as can be eating well and everything. I went back a week and a half ago and bought the 5" XL wild caught one they had (Horatio). I didn't want to buy it first as I wanted to make sure it was healthy and eating which they said it was. It seemed fine but I can't get it to eat any frozen brine shrimp. That's not worring me as much as the tip of its tail has now turned white overnight. The very tip, solid white and its not curling it normally. I read that seahorses are prone to tail rot disease and that it's very contagious. Romeo and Mercutio look just fine. I don't have another tank that the horses would be safe in as my other tank has fish and corals that wouldn't be the best for a horse. I might be able to move the Horatio to my sump in the reef tank, but would his tail rot sickness affect any of my reef fish? He's large enough that he could fit in the sump without getting caught up in the return pump. But I'm just leary of moving him right now. Don't want to loose him. Can I just dose the entire seahorse tank with an antibiotic or something? Any suggestions are GREATLY appreciated as I am about to go to DNA to try and buy something to help treat the poor guy. And I'd like to make sure the little ones don't catch it so should they be treated as well? I'm not 100% sure what Horatio has, but it looks like tail rot. Help please! Thanks! -Mandy
