okay, im not experienced with these fish, so i need a little help. I have a 4 inch rtc who has been in my tank over a week by himself, and last night i added a very small probably 2.5 inch tsn. Will the rtc see him as food? or should they get along? i havent turned the lights off yet, so the rtc hasnt gone into hunting mode really, ive just been feeding him shrimp and worms, no feeders. anyone who's done this before, let me know what happened.
