Ok so i got my sig showing my setup, and my betta is bulging BIGTIME. Hes been fine for weeks in the 37g until recently. I dont do reg water changes, and i think thats it. I aviod doing it because i have so many plantsand i assumed it would be ok. I think im going to do one now. Point is my betta is bulging bigtime and Im really scared of losing him. I moved him to a decently sized bowl, and i was wondering is maybe if this condition was from him staying near the bottom of the tank nearly 99% of the time. Any ideas?
