IT's about 10 inches, my water is pristine and he is very healthy apart from his dorsal fin, surgery was my last option , anything else to try before that would be nice, he is in a 1000 litre tank with 2 fx5 filters , and 2 power heads, any other idears before I take the knife out,Keep the water pristine (large daily changes), add in a vitamin supplement.
How large is it? If it refuses to grow back in a few months, then you'll have to perform some surgery on it! Take it out, cut the damaged fin as close to the stub as you can. It should then grow back more glorious than ever before.
If I do trim his fin is clove oil best to knock him out,
Just keep water parameters in check along with wc's and if any of the dorsal fin was left from the fungus it should grow back.![]()
