so i want to get a 15 gallon salt water aquarium in my room and i know that it will be like 200+ pounds, but i need some help deciding what fish to put in it. I was thinking like 2 or 3 clownfish and maybe an orange stripe goby, but technically there should be 5 gallons per inch of fish, so i'm wondering if i had like double or triple filtration if it would be ok. also i have $240 and i know that i can get all of the stuff for the tank, but if someone could give me some suggestions on the fish i would be thankful. P.S. this is my first marine aquarium, but right now i have a dwarf puffer in one tank and 6 tropical fish in another so this is not my first tank.
