I spoke to Victor about it. He is extremely generous in this case. He said I can moniter them for as long as I want, and he will exchange or ship me new ones if anything comes up. Great customer service.
I saw that thread, by the way. About a goonch if I'm not mistaken. Bummer ://
Now to get these guys on talapia and pellets. So far no luck, but its day one and they are extremely unstable at the moment. Having some difficulty swimming and so forth. I'm definitely not out of the woods yet.
