Hello, Somebody please advice....I got a male betta at the pet store 10 days ago. He is in a 2 gal bowl, with gravel and a plastic plant. I did a first water change after a week and also changed the water conditioner from Kent Freshwater to Aqua safe (as I was told this was a better product). The very next day I found the fish behaving strangely. Movements were erratic and jerky and it was either listless and unresponsive laying either on top or bottom of the tank or "flashing" (rubbing itself against plant - in quick jerky movements). I also noticed a thin film of cottony stuff on its body. The pet store advised me to use Maracyn - a quarter tab every day - which I have been doing together with a quarter tank water change. I use a small syphon to get the water out and refill the tank using reconditioned water. I am nor sure how much of the gunk gets of the gravel though with this method - the water is murky at the bottom most days with the meds. Today is day number three of the treatment and there are no signs of improvement. He is eating okay - I feed 5-6 pellets once a day. Should I add salt? Temp in the house is 80 degrees - so I figured water temp should be fine. Please help. Thanks!
