My swordtail, who I’ve had for over two weeks now, has two fuzzy white patches. One is on his right side lower abdomen and the other is at the base of his dorsal fin.
I’m assuming he is a young fish because he did not have the beginning of his sword when I brought him home. I am am completely stumped as to how he lost a chunk of his tail. The only other fish in the tank are two male mollies (who actually seem to enjoy eachother and are quite mellow), one female platy, one male platy, one female swirdtail and four kulhI loaches. These fish are in a 29 gallon tank with a heater, filter, light and a mixture of sand and gravel substrate.The male platy has gotten fairly aggressive over the last week, but my swordtail was injured prior to that. I actually bought three other female platys in an effort to get him to stop harassing his lady.
My pour swordtail has taken to hiding behind the filter until I turn the light on. I’ve been treating the tank with paraguard for the past three days. I would have treated him sooner but my package was delayed. Also, I’ve been adding bio spira to their tank with every water change.
In the past few days he has perked up a bit in comparison to before treatment, but his fins are clamped, he still stays near the surface, and I can’t tell if his wounds are healing. Also, I haven’t seen him eat in a few day. The thing that is really getting me is the strange behavior he’s doing when any fish besides the other swordtail go near him.This became noticeable two days ago. If another fish approaches he begins to shake/convulse/vibrate and tries to get really close under them and nip or touch their bellies. Whatever he’s doing is very obvious and only occurs when another fish goes near him. Yesterday he was chasing the female swordtail away.
Initially I thought he had an internal parasite (which is why I chose paraguard) and a bacteria or fungus had set in and caused the white lesions. But now I’m not so sure.
Another reason I thought he may have an internal parasite is because his poo’s are a cloudy white/grey color. The only thing is, all the other fish have segments of poo like his but with other colors mixed in. Also, the poos are loooonnnnnggggggg but normal thickness, not stringy.
I’m honestly at a loss of what to do at the moment. Should I add him to the quarantine tank with the new female platys? The male platy picks on him whenever he gets the chance, so do you think the switch would make him less stressed?
All my other fish are happy with their dorsal fins up, bright colors, plump as ever, eating well, and always seem to be in the midst of some very important fish business. That being said, I was worried about the female swordtail prior to treating the tank because she had slowed down, was hiding with her fins partially clamped, and her colors seemed dull. After treatment she has bounced back and swims around the tank and hangs out with the other fish all day, dorsal fin up and bright colors back.
I just want my little man to get better. Any ideas on what I should do?
Literally just did a partial water change, so not sure if tests are even worth adding.
