Well I ended up treating with Tetracycline to be sure and I'm glad I did because it's really made a big difference with his fins. They are unclumping and growing longer, with the ends being either a pale blue or white I've never seen before. then again I've never seen his fins this long before. Thing is the package says it's a 4 day treatment. This was the fourth and final dosage, and while the improvement is quite obvious, he's also obviously not at 100%.. some fins are still clumped and others are still in the regrowth process.
So my question is, do I go another 4 day round or is he fine and the healing will just take longer? The box does say a second round may be necessary.
