AnsleyBleu Posted September 10, 2021 Share Posted September 10, 2021 (edited) Has anyone ever seen "blisters" on the dorsal fin of their guppy before? This guy is over two years old, maybe close to three years old and is the only guppy in a moderately planted community tank right now. Ammonia - 0 Nitrite - 0 Nitrate - about 30ppm GH - very hard Total Alkalinity - 180? PH - about 7.8 Temp - about 80 Edited September 10, 2021 by AnsleyBleu uploaded photos Link to comment Share on other sites More sharing options...

Brandon p Posted September 10, 2021 Share Posted September 10, 2021 I found a post on here with a guppy that has blisters on its fins. Unfortunately there is no answer on that post. If no one answers I’ll give a few ideas. Link to comment Share on other sites More sharing options...
Brandon p Posted September 10, 2021 Share Posted September 10, 2021 Ok and have the red streaks on the sides of the fish alway been there? Link to comment Share on other sites More sharing options...
Colu Posted September 10, 2021 Share Posted September 10, 2021 It could cancer's growths or fluid filled cysts I would treat with epsom salt bath 1 table spoon for 2 gallons for no more than 15 minutes 2-3 times a day it will help reduce the fluid if you see no improvement after 3 days of salt baths I would start to treat with kanaplex in food 1 Link to comment Share on other sites More sharing options...
Brandon p Posted September 10, 2021 Share Posted September 10, 2021 I do think age is part of it. I think it is a gas bubble disease probably caused by poor nitrogen processing in the fish due to its age. The nitrates could be lower so small water change may help. I have read a few scholarly papers I could found and the description is the same all say water quality is the problem, however I don’t think that is really think that is the case here. I would go back to age of the fish and it’s ability to process those gasses. On of the closes things I could find is with pictures is (yes it is not an aquarium fish but does illustrate the bubbles.) there is a picture posted in another post here from May of this year. I could not link it but I tried to include the Author of the post in on it. No answer was find there but pictures are very similar https://www.google.com/amp/s/billingsgazette.com/lifestyles/recreation/fish-blistered-by-high-nitrogen-levels-in-bighorn-river/article_7a546ca7-46b6-5907-a4fc-64ab42ad3745.amp.html I agree with @colu epson salt treatment in case it is not gases but fluids in the blisters. Again I think age is the overriding factor. 1 Link to comment Share on other sites More sharing options...
