Any gudgeon connoisseurs out there?

Specifically, I was wondering if anyone has any experience with purple spotted gudgeons (Mogurnda spp.) in a community tank.

I recently bought a few peacock gudgeons to add to a 75 gallon low light planted SE Asian community tank. The other inhabitants are 5 turquoise rainbows, 13 harlequin rasboras, 4 gold barbs, 4 yoyo loaches, a pair of dwarf gouramis, and a SAE. I loved the look and behavior of the peacock gudgeons (each about 1 1/2 inches when purchased), but the other tank inhabitants would consistently outcompete them for food. I tried many different food types (live, frozen, flake, pellet), feeding different areas of the tank, even overfeeding. They just couldn't keep up with the feeding frenzy and wasted away within a few months.

I was wondering if a purple spotted gudgeon might provide similar gudgeon looks and behavior (and add some more color and activity to the lower levels of the tank), but be aggressive enough to compete for food with the other tank inhabitants. On the flip side, will the rasboras eventually become gudgeon food?

I would also be open to other suggestions to add some more color and personality to the lower levels, in keeping with the SE Asian/Australasian theme and bearing in mind I don't have much more room for stocking. Thanks.

Wow... I had kind of given this post up for dead. Thanks for the replies.

My problem was not with the peacock gudgeons taking flake food (which they actually did pretty well) as much as with every other fish in the tank snatching the flake food from right in front of them.

At this point I am still thinking of trying my hand with a purple spotted gudgeon, but there is only one store in town (Tropical World Pets) that gets them every once in a while. Ordering them off the Internet tends to be much pricier, even before adding shipping costs.
