Ive discovered that my platy is pregnant and im going to leave them in the community tank but... Will rasboras eat platy fry? Or tetras? Im asking this because ive heard that some fish dont eat fry. Normally platies and guppies dont ( so ive heard )
Expect to lose some of your fry to predation. I don't recall just how big a fish a rasbora will eat but a generic tetra includes so many different fish species that there is no telling. Some tetras are tiny and would have trouble eating a platy fry but others could just swallow them whole. All guppies and platies will eat fry but if they are well fed and you provide cover, your losses can be minimal with them.
Neons will not eat your fry. I just cannot remember the appetite that rasboras have, but hets are the only ones I have any experience with. They are among my favorite non-livebearers.
