Completely agree, some exophthalmy (spelling? =buggy eyed) on that young male lippincotianus. It appears that in addition to swollen, there is a white marking on one edge of the eye?
Because you generally maintain good quality water (based on your fishes health through time as judged by your images), it is most likely a physical injury. If so, things like that happen here and there, and get better on their own, provided good conditions. If it were me, I would maintain excellent conditions and watch, or perhaps also add a little salt. But no more for now. Perhaps others have other (better) advice?

Hey

Nice collection of SD's you have there. It's cool that you have several species. They look good in that tank too. In your opinion/experience what is the smallest species of SD? I have a 90g and want some SD's but I don't want giant dinner plate sized fish flying around my tank, lol. Thanks

Thank you. I would say that either the M. Lippincotianus or M. Hypsauchen would work in a small school. Even these will get ~5in though and require really clean water. These can be obtained at reasonable prices when small.Hey

Agree. All Metynnis stay smaller than silver dollars in all the other genera. Among the Metynnis, M. lippicontianus is indeed the smallest, maxing at about 4.5 inches, rarely 5 inches, and most commonly under 4. In addition it is a longish (relatively, compared to the species below, so it doesn't look so big). M. altidorsalis, maculatus, hypsauchen, fasciatus all get to about 5+ or maximum 6 inches.
The 'dinner plates' are Myleus, Myloplus, Mylesinus, Tometes. Those are big!

This is the only one with a hooked fin of the 5 WC M. Hypsauchen.
Very nice fish. Looks to me like a female Metynnis hypsauchen, nicely grown now.
Another species which is very similar, is Metynnis longipinnis, but this is not frequently seen in the hobby. Both have hooked anal fin, high body profile, and long dorsal fin. However, in the (few) pictures of female longipinnis I have seen, the whole anal fin is red, whereas in your specimen, only the lower half is red, making it more like in M. hypsauchen.
In your last picture, the specimen to the right of the hooked-fin (cf hypsauchen) seems slightly different, and is also high-bodied. Could you post a nice side picture of it? Cheers!
