I currently have a 36 gallon tank that's fully cycled and ready for some fish! Here's what I'd like to keep: A school of 6 glass cat fish, 2 emerald corys, a african dwarf frog, and a male betta. Would this be over stocking or cause any problems?
Go to www.aqadvisor and fill out all your information It will tell you if your stocking is correct.
If it were me I'd drop the Glass cats and increase the Cory to 6. The ADF may or may not be good for a betta tank mate seeing that the frog may see the fins of a betta as food. With a 36 gallon tank your stocking of fish type could be endless. But with a betta in the mix you will need to watch what tank mates you include.
