Mummichogs. They are a very common North American killifish which lives in conditions anywhere from freshwater to marine. I have about 10 in my brackish tank. These things are no joke. According to some articles, these have been found in salinities of up to and including 110 grams per liter, (more than 3x the salinity of seawater,) as well as literally being sent to outer space and coming back alive. These things aren't tiny, either. They can get about 5-6" at full size. Not to mention, they eat everything from flakes, to worms, to shrimp, to live fish.

So yeah. They are impossible to kill, usually not very interesting in appearance (the one in the picture is def one of the more colorful specimens,) and very voracious. Not exactly the funnest fish to keep.

So...what's not to like?

Lol, would they be more fun to keep if they were easy to kill? :)
 
No, I sort of just regret getting them.
I mean, I made my bed, so I'll sleep in it, but I was expecting my eel to eat them. However, I guess they were a little too big. I don't have anywhere else to put them ATM, I don't want to straight-up kill them, and it's not worth the trouble catching and donating them at the moment.
 
Most of the fancy gold fish such as Oranda and Ryukin, Flowerhorn. I just don't care for the look of these.
