hello, I recently got 2 fish tanks and started phsycling them. I had 4 guppies and a snail in one tank and in the other I had 2 mollies a snail and 2 guppies. In one of my tanks both of my mollies died. That startled me so I moved my other fish (the guppies and the snail) to the other tank because I knew the water was good and none of my fish died in that tank. I got the water tested this morning and and they said it was good but now Iām worried I have too many fish in that tank and donāt know what to do next. My other tank doesnāt have a filter because I read I didnāt need one, but Iām thinking I definitely need one now! Help! What should I do about my over populated cycling fish tank?
