What poly species did I buy today..?

  • We are currently upgrading MFK. thanks! -neo
Its been beaten to a pulp, but that's 100% a CB Lap. I've seen plenty of fish with a protruding upper jaw. That, coupled with the fact that the nose looks banged up in the first batch of pics, isn't even a question for me.

Update: he has been eating, sort of. Or maybe not.

He'll sniff around a 1cm piece of mussel or shrimp, then chews on it for at least 10 times, then spits it out again.
I thought the pieces might be too big, but smaller ones he ignores completely.

Is he not liking the taste maybe? Or are the pieces really too big?

Help?

OTOH, if he really cannot eat food items that big, he'll probably be fine in my main tank...

And I now have some well-conditioned snails in his tank; THEY are going for the food much faster than he is...

BTW I cannot find any tilapia without seasoning here, and no live worms ATM either.
 
Can you get access to a pellet? Any catfish fillets?

Would just avoid any saltwater fish and shrimp.

Since you're in the Netherlands. For frozen tilapia or freshwater fish fillets. Suggestion maybe to try an asian market/store. If it's not available at a regular market.
 
As far as freshwater goes, I can get pangasius, trout and freshwater "lobster" (they are shrimp-size).

I can give those a try.

I tried various dry food including a pellet for carnivores, he doesn't go for dry food at all.

Also I can get live buffalo worms maybe, they are small but go over well with most of my fish. any objections to those? (I avoid feeding mealworms, lost an archer fish to those once...)

I would try the worms as well, itll probably be a while before he really settles in and will take pellets. but i think with time he will color up. just keep attempting to feed and keep clean water and he should be fine. These are all the regular signs of a stressed poly. I also think as long as you deshell the lobster, probably cray fish that would probably be another good treat.

All I know is that no amount of captive breeding or inbreeding can make one species take on nearly all the characteristics of another. That being said we are judging from pictures alone, so it would be hard for anyone to make an exact verdict. I'm still fairly certain that it's a Delhezi x Ornatipinnis hybrid.

I suppose that the only way to know for certain in this situation, aside from DNA sequencing, would be to look closely if it has a groove running along its lateral line. If it does then it's a lower jawed species, if it doesn't then it's not. Should be relatively easy to spot in person, by getting the right angle in regards to the light.

Also if it doesn't grow much more then it's probably not a lower jaw species.

I can assure you this is not a Delhezi and theyre many way to identify a poly and head shape is for sure not a good one for CB polys as they very heavily in captive bred polys and that seems to be the only argument you are using. The body shape points towards Lap the finlets point towards lap, and markings point turn lap. Also it is highly unlikely this is a hybrid as well.

I can assure you that if I don't have enough experience to identify this poly as a lap the people have already identified it as a lap do. They are as close as they come to poly experts.
 
if the food is too big what I do is put the fish in a food processor to shred it and even the smallest poly can tear off a piece
