I got my betta Constantine about 1 month ago after weeks of preparing a planted 5 gallon tank. He has been normal in behavior as far as I could tell. He's active, always exploring the tank, responsive to any movements outside the tank, always eager when he sees my hand is getting ready to feed him, but I noticed today his fins are significantly damaged. I bought a mirror for him to flare today because he hadn't done so since the first 2 days he was getting used to me, and when he flared I noticed how bad it looked. I hadnt noticed and when I went to see an old picture of him I saw the huge difference. Im going to quarantine him to give him an aq. salt treatment, but I'm wondering how I should keep his actual tank safe for next time. The tank has a Java Moss wall, some Cabomba, Anacharis, Hornwort, a Java Fern, I always keep an Indian Almond Leaf in there, there's some driftwood and he has a ghost shrimp tankmate with a few baby Ramshorns.
The tanks parameters are as follows:
As for water changes I've only done one since Ive had him and it was 50%. I was scared that too much changes would hurt the plants. Is this the problem? Id rather have my plants die away than have Constantine suffer
