Hello people

As this is the first thread I make on this forum, let me introduce myself first.

I am Wim Breukink and am a programmer. I have been keeping fish for about 7 years now. Till now I only kept Malawi cichlids and some L-numbers to keep my fishtanks clean.

Recently(past week) I bought my first rays at a zoo close to me. They are 2 motoro pups of about 6 weeks of age.

Now I have been reading a lot on forums internet etc. but I can't find how a ray behaves in an aqaurium when it is stressed, sick or feeling well.

With my Malawi cichlids I can tell there is something wrong when they breath to fast or loose their coulour without a reason, how do you see this with rays?

I have read that it is normal for pups to dive into the sand once released into a new Aquarium they have done that here as well but after 2 days, I see them starting to swim around.

I have another question about feeding the animals. I have a bit of a problem that the fish that swim alongside the rays in the aquarium, eat the food before it sinks to the bottom, so the past days I gave them some more food that some food does reach the bottom. I am looking for another solution and I see that many people feed the rays by hand, how do I go about to teach them this?

I momentarily feed the rays(and my other fish) Spiring(those small fishes) cut in 2-3 pieces, shrimp and Mosquito larves(red). I don't see the rays eat as aggressively as some videos I have seen, and mostly they aren't really interested in the food, they swim over it, stay a few seconds on top and then move on. Is this normal behaviour for young pups? Or will this change when the rays get more accustomed to their new environment?

My aquarium where the rays are swimming in, is a 250x80x70 aquarium(1400 litres) along with some malawi cichlids before I get questions about that. The water values are okay as well.
 
Hoi Wim,

Welcome to the forum,

I'd keep the young rays in a species tank till they are large enough to eat mussels, fish, shrimp and other large food, later on you can think of adding some other species. Pups really need their food (also adults of course)! I feed my pups 3 times a day red mosquito larvae and blackworms. They are ignoring the food because it's to soon to feed them fish cut into 2-3 pieces. I'd remove all the Mallawi (It's not a good combo either) or put them in another tank by themselves. Also by feeding them more and more so the pups can reach some food, you'd only be polluting your tank.

Don't worry about feeding them by hand for now they are to small, get them to eat and let them get used to their new environment and the rest will follow.

Diving into the sand is normal, especially when they are new, even when they get larger they still like to do it. One more than the other. My Motoro male is hiding himself daily in the sand while my female is always swimming around.

Grtz,
Nico

I've had the same experience with my first batch of pups... sadly, they all starved to death. Try feeding live food, and make sure they don't starve!
 
I would put them in there own tank and keep live black worms in there at all times
 
O Welcome to MFK
 
separate them and give them chopped earthworms, that´s how i started with mine, then when they get fat, try chopped shrimp, today the diet of my two motoros are blood worms an shopped shrimp with the occasional treat of selected feeders (because of infections).

Welcome!!
