Really! My kribs used to kick the flakes out of my ruby shark when ever they got into a scrap. I heard rts are a little more aggressive but I had no idea they could pin down kribs. Leaf fish are cool but don't do a lot. Do you want to keep your adult guppies?As much as I like kribensis, my RTS hates them with a passion. I have one female left from a group and she spent every second hiding in her cave as every time she came out the shark would target her, often waiting by her cave. I moved her recently to a new tank and brought her a little male. She seems much happier and they both chase the guppy fry I have in there also.
Those leaf fish are very similar indeed but not related, right?
