Hi guys! About three weeks ago, my betta fish started acting very lethargic (laying at the bottom of his tank, not swimming around like he use to). He also quickly started losing his fins. There is nothing I can think of that caused him stress to start this. I did 50% water changes for about a week after I noticed the fin rot and that didn't help his problem, so I went ahead and added Tetra Safestart (I was also testing my water levels during this week and I couldn't get ammonia down). I'm currently on day 5 with these readings: pH: 7.4 ammonia: 0 nitrite: 0 nitrate: 10-20ppm Everything points to his tank being cycled. He has been in this tank for five months now, I only use spring bottled water when filling/changing the tank water, and he's eating normally (good sign!). I'm at a loss on what to do. While I'm suppose to wait two weeks for TSS to complete it's cycle, he needs help and everything I'm reading says don't touch the water. He is a little worse this morning, he's opening his mouth while he sits on the bottom. Please, any help would be appreciated. Edit: Forgot to add, he is in a four gallon tank.
