My friend just got a 5.5 gallon aquarium and has a Top Fin 10 power filter. He has 2 goldfish (Comet I believe) that he won from somewhere and has had them in a bowl for about a week. I told him that those goldfish can get very big and eventually, if they live long enough, would require a much bigger tank. He said he wanted another small fish or two but I told him that'd probably be too much for his tank. I'm gonna help him with the cycling process and water quality. So a few questions would be what should he do with the goldfish if they do indeed get too large? (I don't think a bigger tank would be an option for him) Also, I think he could maybe get a guppy or something like that, or would that be a bad idea?
Thanks for any help you guys can give!
