Dovii I in a 125 with other fish will soon have the same out come.
Yup. They grow fast. I have a 150g and wouldn’t even consider a dovii even as a grow out because I don’t have a 300g already up and cycling.
OP-the reason no one says tank size for a quarantine tank is because it’s temporary. Obviously if you have bigger fish, you need a bigger quarantine. I use a 25g, because my largest fish will get 10” full grown. Also a quarantine tank shouldn’t be a grow out tank. Especially for something that grows fast and large.
