A good rule of thumb is 1" of fish per gallon of water. This is just a rule of thumb of course. You wouldn't keep a 10" Oscar in a 10 gallon tank- he wouldn't be able to turn around.

Do you mean you have 18-20 tetra's? Neons and rummy noses? For a 15g, this is probably as much fish as it can handle, and maybe a little too much.

Tetra's are a schooling fish. Usually you would keep at least 6 of a breed to make a good school.

Welcome to the tank!

At this point, you are at the Max of the stocking capacity for that tank, I agree with Meghan (if not too much stocked). Make sure the filtration is higher than the gallon rating of the tank.

Just a word of caution, if you have a Chinese algae eater, be careful. #1, they get larger, #2, is they STOP Eating algae when mature, #3 they can get aggressive towards other fish in the tank (MEANING.. they will start eating the slime coat off of the other fish, hurting them in the process.)

Keep up on the partial water changes, and keep the filter running at top notch condition, feed sparingly, and you should be fine.
