African Dwarf Frog Tank Setup?

So here is my ADF tank setup. I have two in a five and a half/ six gallon tank along with a non aggressive betta. They seem to be doing fine. Then I have a heater which keeps the tank at a temperature of 78 degrees, along with a filter. I have small shells that I keep at the bottom of the tank used as a sort of gravel, and then I have fake plants and a place for the frogs to hide. I feed the frogs dried bloodworms. Is this setup ok?
