i just got a 55 gallon fish tank...but i didn't put anything in there yet because i'm still searching for a non-expensive filter. so i got a lot of time to think of what kind of fish i can get. i really like the" green spotted puffer fish." i heard that they are sometimes aggressive. do any of you have these fish? i also want fish that are unique and different but at the same time kind of cute. can some one give me some ideas of what fish i should get. it would be a lot of help
