i get a small flower ray, but don't eat almost 3 days, every thing looks ok: PH. Nitrate. i try the G-shrimp, earthworm, but don't open the mouth. should i turn off the light at day time or something elth i do wrong ??? need help !!!
Try boosting the temp up a little and leave the tank nice and dark for a couple of days. But everyday try feeding the ray a little and see if it will accept, if not just take out the food and try again the next day. Also try treating it, as it may have internal parasites.
Don't drug the ray yet. There are no signs of internal parasites, so why treat it. He's only had it 3 days. cut the lights, and try offering it live blackworms, raise the temp a bit.
Flowers are sometimes harder to get eating. Like everyone said above but if you can find it blackworms are a must. Hard to find in some spots of Canada.
