if you're still looking for a filter i reccamend the Aqua-Tech 5-15 gallon filter from
walmart. it is one of THE BEST filters i have.
for fish: for get the 1gal= 1 inch of fish
you should get:
1 coreycat
5 platies
4 guppies (remember the2 females to 1 male *about*) this
it so the females aren't overwhelmed
3 mollies or swordtails
or you could replace one group with neon tetras
make sure to clean the tank 1 or 2 times a month
if the tank looks full of fish (like my example) then your good
use you're common sence!!
have fun
