Yea they where all the same size but this guy just didn't grow much at all he is almost the same size while the others doubled in size.azul. keep in mind you can buy a group of 6 and there are times you might get a runt.
I didnt quarantine but i had a small worm problem that i believe was caused by overfeeding. I medicated the tank with prazi pro and less food. I thinj any parasites would have been removed witj tratment i think.If your bass is eating but not putting on any size, it could be internal parasites. Have you put them through proper a medicated quarantine at all? If not I would deworm him and your other fish as well.
