I used to feed my Chalceus crickets and they loved it.
Good to see someone else keeping Chalceus spp on the forum. Have you taken the time to be sure whether they are pink tailed chalceus (C. maculatus) or the gold finned chalceus (C. erythrurus). In my experience the latter are somewhat more common in the hobby, but the shops tend to label them as the former.
I've always believed it to be a Chalceus Macrolepidotus (which i think is Pink Tail?).
It's the spitting image of the one here

I didn't do my research and got 3 of them quite some months back, didn't work as i am sure will not suprise you. Re-homed two. Kept this one, it's a 5x2x2 and is only skittish during water changes, bright pink/purple tail. I have quite a few recent picture's but am on a lap-top right now. Will upload some later tonight Andy and perhaps a video clip and you can let me know what you think.
It is in with Parrots (which may offend, lol), Rope Fish, Rainbows and a 3" Datnioides Microlepis
UPDATE on the foods
Well i purchased
x8 locusts at 15p each and also a small tub of "
wax worm" for £2.50
The locusts are about 1 inch and the worms about half-inch.
I aware feeding locusts is not unusual for certain fish, but not sure of wax worm so will research / ask around before i use them
So i far i have dropped three locusts in one at a time. The Pink Tail got two of them and one of the Rainbow's munched the other one.
Actually it's the first time i have ever seen the Pink Tail take food from another fish (he snatched one locust from a posse of Rainbows) so this is encouraging as usually the Pink Tail is very passive at feeding, a very polite eater maybe a bit too polite sometimes.
EDIT:
from a quick look about on net, Wax Worms seem pretty safe for fish, high in protein, although a little fatty so be used more as a "treat" from what i understand
.............
okay some wax worms have gone in, Chalceus has eaten a few of them, and actually i saw him pursuing a wax worm that a Rainbow spat out and it's very rare to see the Chalceus in the bottom half of tank, even for prawns or bloodworm he wont go past the upper half level of tank but he did for the wax worm.
Rainbows are munching quite a few, so larger worms like meal worms might be better here?
Parrot's showing no interest in worms or locusts which is good as they are dominating too much at feeding time generally.
