Small cactus garden

[duckduckmooses]

I have a ten gallon glass tank I'm looking to plant something in. I posted over in flowers, but cacti are another option for me.

I'm alright with anything that will stay small and be able to stay in the tank. flowering cacti are preferred.

I don't really know how growing and caring for cacti works, so any advice would be great.

I am kind of a cacti and succulent noobie myself. I just use the bagged cactus mix at lowes/homedepot. I mixed a little gravel with some cactus mix for a succulent I just transplanted. I think they'd work nice in a container like a fish tank, but the only problem is drainage. You are gonna need holes on the bottom.
