Hi..i am new to this forum, but i love all of the information that i have been able to find to help me to become a good mom to my betta, jackfish. i bought him approx ten months ago from a local petstore(dont know if its okay to name names). i am embarrassed to admit that most of what i have learned about my beloved jackfish is from this forum-i realize now i should have studied more before i bought him. anyway, i am writing because it seems i am doing everything i can for jackfish, but that i am always battling some issue or another. i feel terrible. he has actually been a pretty active and healthy betta, but today i noticed in the area behind his would be chin, is all swollen-huge- and i realize again, that i have so much to learn in taking good care of him. most laugh at me and say that he is just a fish, but i am absolutely and totally loving my first betta, and would just hate it if anything happens to him. What am i doing wrong? he is in a three gallon tank by himself. hes red white and blue. i do a 50-75% water change, every two weeks, and about a 25 percent on the in between week. i use water conditioner every time, and i have battled dark brown and black algae more than i would like to admit. i keep his light on only eight hours daily now, and he has a heater too. he eats pellets..every morning i give him four or so. hes the cutest and most lovable fish i have ever had, and need and appreciate any help or advice..as i would do anything to keep him happy and healthy. i swear, he greets me everytime i go up to the tank and shimmies around.its the cutest thing ever. anyway..i am very concerned that he is so bloated-i guess the gills? where his chin would be, if he had one. thanks so much...jackfishs mom
