As the title says...
My tank is cycled (Can't do any more testing though, the API master kit went into oblivion. Great waste of money.).
He's in a divided 5 gallon, I do two 50% water changes weekly. Filter works fine. He HAS suddenly seen his neighbor betta, and for about 6-8 days went through an insane amount of stress. Started tailbiting, attacking the divider (it's plastic mesh) continuosly. Now he's finally stopped, tail his growing nicely, still interested in the neighbor but no more attacking.
Today during the water change, i noticed two white-pimple like things under his jaw. Very small, white in color. The pop out, but it seems like it's coming out from under the skin (so it's no ich).
Water temperature is at 77, using a (regrettable) preset tetra 2-15 heater. He's been with me for about 1 year. The time I got him at the pet shop though, he was considerably larger than the other bettas. He's always had health issues (constant fin rot coming back, funny behavior) but non recently for the past few months, aside from fin rot.
Nothing is different. He eats just fine, he swims just fine, he comes up to me just fine, no change whatsoever.
Worried about him, I don't want to lose him yet... I know he went through a lot of trouble, too. When I got him, I could tell he went through ammonia he** since his upper tail was so insanely curled.
Frankly...what should I do?
