This is not a disease or emergency yet, but they say an ounce of prevention is worth a pound of cure...and it's hard not to be sensitive about our little "Betta."
Gravel bottom, live plants and some ornaments (see picture). Recently added some mopani wood that was boiled several times the day we got it and is still leaking quite a bit of tannin.
Heated, 80 degrees
Only one tankmate, a recently-added bristlenose pleco. They seem to mostly ignore each other.
Rotation of Bio-Gold pellets, some generic betta pellets, freeze-dried bloodworms, freeze-dried shrimp, and frozen peas
Once a day, 3-4 pellets
We had been on a bi-weekly water change schedule, but in response to his behavior we just did one a week apart, and most recently a 33% change just 2 days after his 50%.
Usually the water change is 50%.
We have not added anything except water conditioner until recently (see below)
Tested earlier this week
Symptoms and Treatment
His fins appear to be more worn than usual, but primarily he seems very listless and routinely sits at the bottom of the tank. His breathing appears heavier than normal as well. He is eating fine and reacts to our presence, but it takes more prodding than usual and he certainly does not have the same energy he used to. The situation is not dire but I've read about some similar situations that go south from here...
We first noticed the symptoms about two weeks ago, which seems to have coincided with the introduction of the pleco and mopani wood. I did not quarantine the pleco so there is a lesson I learned there. In terms of treatment I just started giving him a little bit (1/8 teaspoon each) of melafix and stress coat. We are going to do 33% water changes every few days now. He is probably about 1 year old and has had some melafix to treat small tears in his fins, but has otherwise been healthy.
Is there anything else I can do besides what I'm doing now? Thank you so much for your time.
The pictures show the setup, him sitting on the bottom of the tank (which he is now doing most of the time), and a close-up.
