Hi,
I have a 15 gallon tank,w/an air stone,Penguin 150,tank lined w/stones and 3-6" artificial plants to one side of tank and a hood w/light. I will also treat the tank w/BIO Spira before getting the GF(goldfish).
I hope to put two goldfish in the tank but need to know which type of goldfish I can get that will not out grow the tank. I've read that they need a lot of room but I 'am hoping that some one can suggest a type of GF that will not outgrow the tank.
There is a lot of data on GF out there but I feel better asking 3reef members.
Thanx
