@Kfry - I used to fed them once a day but larger amount. But with the last 2 bettas I feed one pellet 2-3 times a day, particularly the current one and because I want to monitor their eating. He just ate a pellet not to long ago but its been a few days since he's touched anything else. I will give bloodworms once in awhile just 1-2 for a treat.
@sena - No, actually have no clue how to test the water. I know you buy some sort of strip and put it int he water and I think it changes color to let you know the levels in your water, but I have no clue what would be good or bad levels. I know the city has had issues with the water in the past and has alot of chlorine (the odor is overpowering) but I do let the water stand for 2 days and use conditioner before putting fish back in.
I put the salt in when I do the water change but I let it dissolve for 2 hrs before betta is put back in tank and I haven't been using it that much anymore.
