I feed my overpopulation of guppies to my angels. Angels are natural hunters and will hunt down the babies. It's enriching for them and they help me out by thinning my guppy population lol
I seriously have an assassin I see once a year, if that. He'll pop up occasionally and I'm like "oh, hi buddy. Glad you're alive. Sorry there aren't any snails in here for you to munch on right now." And then he disappears again and I think he's dead until he decides it's time to pop up again lol
Well, thank you guys for giving me extra knowledge, I appreciate that. Perhaps I will use real plants in my next tank. All of my prior bettas lived for five plus years so I figured my care was already as best it could be. I guess I can improve lol
