Symptoms and Treatment
How has your betta fish's appearance changed? Was bloated, now looks fine, but skinny
How has your betta fish's behavior changed? Lethargic, not eating
When did you start noticing the symptoms? Was acting odd 1 week ago, shortly after my crowntail in an identical setup died. The symptoms are really similar to the crowntail.
Have you started treating your fish? If so, how? Dropped the water level to about 4 inches so he could get to air easier.
Does your fish have any history of being ill? Was really lethargic for a month or two after I got him, found out he needed a higher temp.
How old is your fish (approximately)? Bought full grown from petco 8 months ago.
I just lost my crowntail a week ago, he was spending a lot of time just sitting at the bottom of the tank, not at all like his usual spazzy self. My surviving fish is starting to do the same sort of thing. He also has been swimming around fine for a while, then stopping and just sinking to the bottom of the tank. He keeps his mouth a little open while he's doing it and while he's sitting at the bottom of the tank. He looked a little bloated an hour or so ago, and I had read somewhere that you can use a mirror to make them flare and poop. He flared up and was feisty for a while, but I never saw him poop. After that, he didn't look bloated any more. I had put food in for him a couple hours ago, before he started to look bloated, but he didn't eat it, so I pulled it back out. I lowered the water level to about 4-5" since he didn't seem to want to stay near the top of the tank. Normally if he's tired, he sleeps on top of the heater, but tonight he's either at the bottom of the tank with his mouth open or in his little terracotta pot. His gills are moving a little, but it doesn't look like he's gasping like ammonia poisoning. Is there anything I can do for him?
