I have had my betta fish for 6 months now. Was so happy, making his bubbles in his bowl on regular basis, eating everyday, keeping him clean. So he was good and happy with the care i provided for him, simple! Now for the past week, he hasn't eaten at all, and digging his face at the bottom, barely moving, won't come up no more to see us not to even have food. Only seldomly he will some swim like crazy to the surface like he's running a marathon then goes straight back to rest at the bottom. On second day, he has been breathing heavily non-stop and i have noticed also his tail fin started to split, so I went and got some BettaFix, been adding this to his bowl for 2 days straight now (directions says to keep up for 7 days) while i change his water every day and also, I am now adding NutraFin Aqua+ to help improve the tap water quality. I want my poor Picolo to come back healthy, I don't know what went wrong. Please someone, I need to hear from you if you have had similar experience with your betta fish. Thankyou.
