Flashy Fins
New member
Need some advice. I think I'm dealing with flukes and want to run my game plan by others before I start, in case am I missing something obvious. Clearly, I've made some mistakes along the way if I have flukes in my display, so here I am.
I've had 2 fish die recently, I suspect from flukes. The first to die was a green banded goby (Elacatinus multifasciatus) who showed ragged fins and breathed slowly with his gills open wide for several days, then went into what I can only describe as a full blown seizure before death. This was not merely a few twitches of his head; this was his entire body jumping and flipping around, sometimes landing him upside down (which he did not seem to notice or could not correct on his own; another spasm would soon flip him upright). The fish did not breathe rapidly, did not come to the surface to gasp for air, did not show any spots, etc. His only symptoms were ragged fins, slow and large breaths for several days, then the seizure before death. He was somewhat lethargic the day he died, but not dramatically so. More than a week later, the same thing happened to my tiger goby (Elacatinus macrodon), the only differences being less ragged fins but a much more intense seizure. Flukes are the only explanation I've been able to come up with, although that is only a researched guess. Corals and inverts all seem fine.
Other fish are showing a few other symptoms. My mandarin suddenly has some sort of growth or fuzziness in the middle of her tail, different from the ragged fins the gobies had, but I've read a sign of possible flukes. A couple of times lately, I've watched one of my blue striped pipefish rub his belly against algae growing on the glass, but it was only for a moment each time, possibly an itch, with no other symptoms. Everything happening could be a result of flukes, from what I've read, but other educated guesses are welcome. If this is something else, I need to know what I'm dealing with.
Fish in the display:
1 mandarin
1 ruby red dragonet
2 blue striped pipefish
1 green banded goby
May or may not be important, but I believe the flukes came in with the green banded gobies. I started with 3 juveniles about a month ago, and they all had ragged fins when I bought them. I didn't think enough of it at the time, figuring it was just from them nipping one another. In hindsight (always 20/20, right?), I never actually saw them nipping at one another and should've realized the ragged fins were a sign of illness. 1 of the green banded gobies died, as noted, 1 disappeared never to be seen again, and the third is still in my reef with ragged fins. Regrettably, I only QT'ed the gobies for a week, with the thought that they needed to be in a reef with live food, given their tiny size (each about 0.5" long).
Given the diet requirements and difficulty of catching these tiny fish, I prefer to treat in my display tank. Assuming no one identifies this as something other than flukes, I'm planning to dose Prazi. I've never used it before and have two some concerns:
I have a coco worm in my tank. I know I need to remove it when treating, but I'm wondering if it will be safe to add it back once enough time has passed? From what I've read, if I keep it in a fish-free environment, 8 days should be long enough to take care of any adults or eggs. (Please correct me if this is not true.) How should I care for a coco worm living alone for 8 days? Should I target feed it?
I also have concerns about reintroduction to my display via pod cultures. I culture tisbe pods in gallon jugs with old tank water and am now worried about flukes or eggs in those cultures. Does it sound like a good strategy to combine the cultures, treat with Prazi the same as if there were fish in the water, and use sterilized containers when I separate them after treatment? Or should I just continue culturing as normal, but not let any water go from display to cultures (or cultures to display) for at least 8 days? All of my fish eat frozen food, as well, so I think they could make it without me harvesting any new pods for them for that long, but I need to be sure my cultures are fluke free once I do start harvesting again.
