Blister like lesion


Recommended Posts

Hi guys

Few days ago i bought a pearlscale goldfish which seemed totally healthy and fine. Ate food well and everything was ok.

after 1-2 days some small red spots appeared on his skin and i tought it could be a kind of invasion by other fishes since it seemed really like being nipped.

they the red marks started to develop within 1-2 next days and then small blister or bubble like lesions appeared on his body and now all the scales seem inflated and the fish does not eat well as before.

now i am think of it may be a kind of parasite or bacterial infection since the other goldfish in the shop has also now developed these blister like lesions.

i havr started metronodazole treatment with a dosis of 20mg/gallon and the red marks are now less but the bubbles are growing and still the fish does not eat well.

is there any adivce you can give me please????

does any body have experienced such a thing before?

Bubbles on a pearlscale indicate dropsy. Dropsy is generally incurable. The fish was sick when you got it. Return it to where you got it from with the other sick fish in the shop, never shop there again, and nuke your tank and search for healthier stock.

And some pearlies just get them seemingly asymptomatically. It’s very hard to tell until or unless things decline whether they’re the harmless kind or the indicates-trouble kind, but I agree with Mj, Pearl scales are distinctly difficult to treat if they’re dropsied.

 

if you can fill out our diagnostic form and provide some pictures I may be able to tell you a bit more.

I do want to reiterate, though. We can treat, as this sounds like it’s secondary to an infection if there are red lesions too, but the likelihood of treatment working is very very low.
