I just got a brand new 20 gallon from a friend and I need to know the best brand of filter and heater for this tank to keep my fish happy and healthy, cheap but good would be nice
by budget is around 25 dollars for a nice small filter and 25 dollars for a heater.... I know its a really tight budget but its a small tank so it doesnt need heavy equipment since it will be filled with tropicals.... thanks! please post!
