the foods i feed rays are 98% all freshwater based foods... Potamotrygon comes from fresh water so obviously they eat fresh water foods...


Shrimp is my main diet
Pellets are next or first depends on my mood that week
pellets are mixed hikari i feed carnivor massivore and sinking algea wafers for something different

i also feed silversides and smelts(i try for freshwater smelts when ever possible...
freshwater clams scallops (usually i raise them for awhile)
i also raised my own live shrimps and gut loaded them on pellets and would feed at will( really stimulates the rays just size the shrimps to the rays)

i have fed squid as a treat as well... lots of people will feed tilapia and other fish fillets my theory comes back to the whole fresh water salt water deal..


worms are also a big food for alot of people... me i use them short term and move on to other foods...

Blacks worms and red wigglers are great for small young rays then you have night crawlers
african night crawlers are great food source but get very expensive... me i prefer prepared foods as it keeps life more easy

Yea cheers for that nic,

I use hikari massivore, sinking wafers and Cichlid bio gold (sinking pellets).
I mix it up between them.

Tilapia are freshwater fish.


They are known to tolerate high levels of salt but are in fact African cichlids.

I breed Oreochromis Mossambicus as a food source for my ray.

I believe in a 100% freshwater diet.

Yes, they are freshwater fish. The species I breed is Tilapia(Oreochromis Mossambicus).
Oreochromis mossambicus is an African cichlid and is found in a variety of areas including Lake Tanganyika and Lake Victoria.
If you've ever had Tilapia at your favorite seafood restaurant, Oreochromis mossambicus is the fish you ate!
They are incredibly prolific. It will breed even in poor conditions. Even when food is low or nearly unavailable, this fish will continue to breed. It starts to breed at only two inches! They are also very hardy and can tolerate levels of salinity equal to that of the ocean. It eats just about anything including algae and detritus thus exploiting a food resource not used by most native fishes.

I am surprised that no one has tapped into this wonderful food source for rays before.
The fillets are cheap and readily available but I am sure rays would much rather eat live juvenile Tilpia instead.

if you look the world over... some breeders have special mixes but the most widely used food is shrimp and pellets... most people rather stick with what works and keep it simple...

This is very true. Most are actually grown on large Aquaponics farms.

sorry to be off topic but does anyone know where to get any Tilapia in Australia.
i got a spotted gar who is eating his body weight in feeders... and they charge a mint here for them. drop me a pm if you know anything. (looking to breed low maintenance stuff)

plenty inside paddy's markets at Haymarket in the fish market.

from what i have heard, some just turn yellow some stay white.

U cant beet quality pellets for nutritional value, so i wouldn't stop using them or anything.
