Any particular reason for that line of thought? I think it's pretty nice actually. Hell I bought some FW fish at Aquatek this weekend and they don't guarantee them, PERIOD. I've already had one die (this morning)... so I may have well have put $3 in my shredder as far as I see it. With Petco I could have taken the poor corpse in for exchange/refund.
Poor little tetra
i say this because i had a hard time returning my pseudochromis because he terrorized and nearly killed everything in my tank, but their "policy" was no returns on saltwater fish because they are not guaranteed to survive acclimation. i stated that in the nicest way possible. (this also was an impulse buy. he was so pretty though lol)
i'm glad they helped you out.
