Weird bubble like thing growing...

So my son’s betta died about two weeks ago, so we bought a new one. We have had the new betta a few weeks now and this bubble like stuff keeps growing around the uneaten food on the bottom of the tank. I have cleaned the tank a couple times and it keeps growing back. We never had this issue with the previous fish for the two years we had it. What could this be?

yup, it's bacteria! I'm pretty sure you're over-feeding too. Like Mbpoppy already told you, uneaten food needs to be cleaned up immediately. If it's left to sit it will cause ammonia spikes which can easily make your fish ill or even kill it.
Is there a reason this is happening now? We never had this issue with the previous fish with uneaten food.
