the natts i have are my first ever. I really wanted the caribe since People all over YouTube say red belly’s are skittish but after only a week my red belly’s come up to the glass to check me out So I’m happy. I’m always sitting next to the aquarium to condition them to me.I have kept Caribe over the years and there is usually some level of loss when they are juveniles. If they get babies in at some point in the future then I may give it another shot. Tough to justify a $500 to $800 shoal when there are no guarantees.
