This might be a dumb question but are rays night eaters like catfish ??? The reason i ask is because i need to fatten up one of my rays by powerfeeding him but it's hard to get food past my aro's all the time..(yes the aro's are for sale so they won't be in there for long) But was just thinking if i could feed them at night maybe i could slip the food past the aro's with out them seeing it.. Thanks..
