Ok everyone, its me again....with yet another problem. And I am apologizing ahead of time, because this is going to be an extremely lengthy post Ok, so, my betta. He has been doing great until Friday (the 3rd). That is when he started to not look so hot. Lotus gave me a link about betta diseases, etc. and that helped me to narrow things down as to what might be wrong with him. His fins were clumped (i.e. they werent fanned like a happy, healthy betta), and his gills were red, and he was extremely lethargic - this all occured after the temperature of his tank had elevated to 86F (for an explanation see "Fuzzy stuff.....sick fish?"). So, i was thinking he had "simply" been overheated.....aka: was being cooked to death!! And, according the website, he didnt have any other visible disease, but was showing signs of depression...I purchased an amonia water test kit, a nitrite water test kit, and a nitrate water test kit (Line: Nutrafin, Distributor/Company: Hagen) - the kind with the test tubes and dropper bottles. Everything seemed to checked out ok (NH3: 0-.1mg/L; NO2: less than .1mg/L; and NO3: 5-10mg/L ). But, even still, I did my weekly water change (about 25-30%) Saturday night (using my usual RO water and stresszyme) and I used an aquarium sponge to clean the sides of tank a little bit (I had some algae growing). That seemed to help with his mood. He started to swim around more actively the next day and was looking great - no more red gills and his fins were fanned . He was also eating quite heartily which was an amazing improvment from Friday when he wouldnt touch a nip of food (Saturday morning he did eat but he threw it all up about 5min later, this was before i did the water change - that was done saturday night). He ate this morning, which is good, but he looks soooo bad right now. He is rather lethargic again and his fins are all clumped together again, his gills are now splotchy bright red (not completely red, just patches), he seems to be struggling for air - almost like he is suffocating, because he will be towards the bottom of the tank and start flarring his gills extrememly (at 90 degree angles) and then swim around kind of crazed and finally find the surface and take huge gulps of air....now i know that is not good. I have the top of his tank slightly removed to allow for more surface air, hoping that maybe that is the problem...I'm at a loss as to what I should do now. Could it be a parasite of some sort? Is there something wrong with my water quality? pH? Any suggestions would be greatly appreciated. Again, sorry this is so lengthy, I just wanted to try to give yall everything you needed to know now so that you dont have to keep asking later Thanks.
