Hello everyone I'm new to the forum so heres a little about my situation:
I have one betta (Cosmo) in a 1.5 gallon tank. I would like to have him in something bigger but my dorm room wont allow it. He is fed about 2 betta bits pellets twice a day. I have had him for about nine months and have had no problems untill now. I change about 50% of the water everyweek. I noticed on Sunday that Cosmos right eye was kind of bulging out of his head and had a whitish film over it, he also didn't seem to want to eat. After doing some research I'm pretty sure it's called popeye. My local aquarium store prescibed Maracyn. I've been putting the recomended amout in his talk since monday so today will be the third dose. It says to use 5 doses total. I'm worried because while he is more active today than he has been in the past couple of days, he is still not eating. He tries to but its almost like he cant see the pellets, he swims around underneath them but never actually grabs one. He did finally get one this morning but then spit it back out!!! I'm sorry for such a long post I'm just confused and worried about the little guy

any suggestions would be awesome!
