Odysseus has now been battling fin rot and/or torn fins for nearly 5 months. I've replaced his plants with all silk (2 months ago), I do the water changes...I've tried aq salt (backfired badly, twice), 3 rounds of kanaplex, I just don't know what to do.
He did beautifully when he lived in a 1 gallon (which probably had closer to 0.75 or 0.8 gallons of water actually in it) with plastic plants. But that was also in a place where the water is only slightly hard.
Where I live now, the water is VERY hard. It is also quite alkaline (ph= about 8.2, sometimes a bit less). He also lives in a 3 gallon tank. I moved him about a month ago to his 1-gallon hospital tank after he had started to lay around on the floor of his 3 gallon a lot. He perked up, although he was badly constipated for several weeks, but is now looking even worse. His tail is badly split and all his fins are in terrible shape. There's often red near the edges of the fins, but no obvious lesions, sores, kinks in his spine, etc.
I've tried water changes of all sorts of frequency. I've tried Jungle Fungus Cure, Kanaplex, Epsom salts, Aq. salts. I;ve not tried API General Cure, Triple Sulfa (but I have them).
He still eats well, but he's become fearful and lethargic.
I don't know what to do anymore.
