Help! My son's betta Rock N Roll is the tiniest, sweetest little fish ever and he is really not doing well. He had been ill for several months with chronic SBD-like symptoms and took a sudden turn for the worse a couple of months ago. I thought he was dead at one point, and he seemed to be suffering so much that I considered euthanizing him. He miraculously recovered, though, when we lowered the water level in his tank and raised the temperature and has been thriving for the past two months or so.
Earlier this morning, I found him lying on the bottom of the tank. I could see his gills barely moving. I put some pellets in to see if he would eat them, but he didn't. He swam around weakly a couple of times, but never very far and always coming back to rest on the bottom after a few seconds.
Remembering how much lowering the water level helped before, I have lowered his water level to maybe 1.5 inches of water. When I did that, he did manage to come to the surface a couple of times but was still refusing food. I also laid a silk plant on its side nearby so he could rest on it if he wanted to. I figured I would give him some time to rest/recover but he is still in pretty much the same condition and I don't know what to do.
He was fine last night - swimming around vigorously and ate around 8 p.m. when my son fed him. There is nothing visibly wrong with him - he looks the same as always. The only thing I can think of is I suspect that my son may be forgetting a good number of the morning feedings because now that it is summer vacation, he is still asleep when I leave for work and I am not here to remind him to feed the fish, so maybe because he is so tiny (he is literally half the size of all the other bettas we've had) he is weak from lack of food.?
