I went to look at a cheap red aro tonight, about 30cm long, and it looks like the right eye is starting to push out at the top. The guy said "it only does it sometimes", but in the 20 minutes we were there it was always looking down. Is it likely to be the start of drop-eye? I know its not as common in asians as it is with silvers, but I presume they can still get it. Is it more common with lower grade fish? The price is about as good as it gets (just over half what they retailed for when they were imported about 8 months ago), but I don't want to be stuck with a fish with drop-eye...
