Royal gramma recently developed some fraying of his caudal fin a couple weeks ago, at the same time he seemed to become more aggressive towards his tank mates, especially a Midas blenny. I initially attributed the fin trauma to aggression, but never actually witnessed anybody attacking him—quite the opposite as he seems to instigate with the blenny who hilariously completely ignores the gramma. Only recent additions have been inverts…a few emerald crabs right before I noticed the fin fraying. And some corals on frag plugs, all dipped in CoralRx.
Over the last week or 10 days I’ve noticed the gramma flashing/scratching on the rockscape. Eating, swimming, still trying to bully the Midas. This is a young tank, gramma has been in the tank since Dec 1 and was quarantined/medicated by a reputable seller. The other fish are the Midas, a Banggai, a Yasha, and a court jester goby. Other fish seem to be ok. Nobody else scratching.
I think the gramma has a small white area near his tail, just noticed today, oval shape, fairly difficult to see. I’m thinking about treating the DT with Prazi on the assumption this is flukes since whatever it is hasn’t rapidly killed the gramma and all fish were quarantined and medicated (let’s assume for now that this protocol was adequate), and flukes can ride in on inverts.
Treating with Prazi seems pretty low risk, I think removing the gramma from the DT is going to be difficult and stressful. Just wanted to make sure my line of thinking is logical, and see if anybody has other ideas…also is the tail fraying indicative of anything other than nipping by a tank mate?
