I'm tired of issues with my 10 gallon aquarium... My current question is - why would a fish have his chin extended? See picture for what I mean... My betta just started to show this extended chin the other day (I'm pretty sure yesterday soon after I fed him). I think he may have spit up one of the pellets as well. Today he won't even eat and one of the recommendations given from my LFS was to start feeding him more than 3 times a week. I can't do that if he won't/can't eat. Poor fishy. Also, he is now staying at the bottom of the aquarium and moves only to gasp for air or to move more under his driftwood "cave" (which really is just the back of it where it goes in slightly). I plan on buying a breeder's net tomorrow, but currently he is in that cup from the picture floating in the tank. I don't want him to drown if he can't get to the surface in time. Water parameters as of yesterday before I did a water change (did another change today as well) came back with pH finally coming up from 5.5 to 6.4**. Ammonia is back in a small quanity (I think it was .25ppm), there are no nitrites, and was nitrates (not sure exactly since they used a test strip for that part -- not the pH or ammonia though). Also, KH is around 40. From the test strips, I've seen it even go up to 80. The tank has been up and running since June 2011. It is a planted aquarium. Also, I do water changes (25%) on a weekly basis but will start attempting them two or three times a week.
