Stingray Feeding Studies in their Natural Habitat

  • We are currently upgrading MFK. thanks! -neo
Yeah, I was going to say the Mazuri Stingray Gel should be a good option, but sometimes hard to get your rays to eat.

Ghost shrimp, worms, and pellets seem like a good variety in comparison to fatty seafoods such as fillets and prawns. Pellets might be varied but I wonder if we should be careful based on the fact they are designed for high protein carnivores like catfish, and rays digestion might not be able to handle lots of these, especially in captivity since we control their ambient temperature and it's very constant.

For example, a ray in the wild that feasts on a large amount of high protein meaty foods would have the option to move into shallow water and bask in warm water to speed up and aid in digestion, much like reptiles do. (Rays are coldblooded).. but in captivity, most tend to keep them in warmer water as it gives a beneficial effect, but this could actually be straining their body as it's not needed 24/7, but only for digestion needs.

Keep em coming guys ;)

feed pellets...hikari.

they will get a variety of vitamins?

To be honest a pellet diet for rays is not good at all, they need a well varied diet I only feed pellet food once a week.

i don't understand, i feed hikari daily and would think that since it has a variety of vitamins it would be the healthiest. I feed shrimp and worms to some of my other fish and sometimes my rays get some too. But never feed black worms or ghost shrimp for fear of parasites.

There is to much protein, fat etc in a pellet diet for rays in my opinion. What about calcium how would your rays get it from pellets? they would need some type of fish whole silversides or smelt.
