Fluffy Weird Clumps In Tank?

    Hi we started cycling our new 25 g tank. We started the tank cycle using 50% water from our established tank, added good bacteria and let it run for a few weeks. The was what appeared to be a bacteria bloom. Once the water cleared and the water levels came out right for fish we added our shy Platy. About a week after this we added 4 guppies and 5 cardinal tetras. Within less than 48 hours we noticed foam forming at the top. I immediately worried about soap so we moved the fish to a rescue tank. 2 guppies died and 2 cardinals. Long story short once we turned all the agitation off these clumps of puffy film appeared and started to settle to the bottom. I don’t know what it is. Just really curious. Any ideas?

    Did you ever have any driftwood in the tank?

    No. Nothing but artificial decor and we rinsed it before putting it in.

    We figured it out!! Too much of a good thing. We added too much good bacteria. We added already established tank water and put enough bacteria in to start a 40 gallon tank. It’s a 25 gallon tank. So yeah.
