Oscarum monstruoso;4934136; said:I bought a baby jag that had one of its fins torn off, great pet. People keep blind, stunted and deformed fish all the time. Its not a factor imho.
You're forgetting that MOST fish keepers will NOT buy a sick/deformed fish, theres exceptions to everything.
As for the people keeping those blind/stunted/deformed fish, Most of them only keep them because they were hurt/disabled under their care.
I doubt anyone that has the mindset of "Hmm, I think I'm going to buy a blind/ugly goldfish today" before they walk in a lfs.
