Well, after all the guppies my sister was "keeping" died from apparent inbred diseases, she never bothered to get back into it. She told me today that even if they had lived the maintenance was too much for her... so I have an empty 6 gallon eclipse tank on hand with some pretty sand substrate. Any suggestions? I was thinking 5-6 goldfish or something... Just checking to see if you were paying attention.
Seriously, though, I'm kinda stumped. Guppies are out of the question after this experience with them... I understand that my options here are extremely limited. No bettas either; I already have one and he's awesome! Thanks for all the suggestions!
