Fish question, need lots of answers!?

your feeder gets over a foot of length and black moor goldfish will get half foot of length your tetra 2.5 in. your female guppy is going to stay 1 in. With proper care these guys could live up to 10 years not sure about the tetra. Even if your frog doesn't eat your fish now it will soon eat your tetra and guppy as they get very large. Your tank is too small for your aquarium your goldfish length would probably stunt and may die at a much more early age. Your goldfish can get your other fish sick easily too.
