I know that it is way to small for a pleco. Heck even if the pleco was the only fish. But for some visual variety and maybe tank clean up duties I have been thinking of getting a snail.
What I don't know is will the snail do more damage then good? My hope would be that it would help control algae, maybe clean up the bottom a bit (although the cory seems to do that well) But my load is probably a bit overstocked as is and I don't want to harm the balance any.
Hello and welcome to AA!
You are definitely correct in thinking the snail will do more damage than good. Your tank is quite overstocked.
Most cories need a tank of atleast 20 gals. They are shoaling fish that should be kept in groups no smaller than 4.
Glofish need a tank atleast 30" long (this is a 20L or 29). They are schooling fish that should be kept in groups of atleast 6.
Pearl danios need the same, but really longer is better, these guys get huge. Yours will most likley develop a hunchback if kept in such a small tank. They are also schoolers that should be with atleast 5 other of their own kind.
Dwarf gouramis need atleast 10 gals.
These only fish I could recommend keeping in a tank of this size is a betta, and even then a female would be best. Possible a small school of chili rasbora depending on the dimensions of the tank.
I would recommend you get rehome these fish if you cannot set up another tank for them right away. There is no way that so much waste being produced in that small of a water volume with a tiny little filter can be healthy for the fish.
If you aren't familiar with how the nitrogen cycle works and how to cycle a tank, here are some helpful links: The Aquarium Nitrogen Cycle
, I just learned about cycling but I already have fish. What now?!
