ThanksThe dilemma of "true" predatory" fish in captivity. I say "true" because other predatory fish say like triggers, can be somewhat domesticated. If you remember me mentioning this dilemma in some of my writings in regards to feeding live food. A natural instinctive predator will start to tuck away and just wait to be delivered food as their natural hunting instinct dies. Yes managing feeding can help but the real challenge is to create some kind of enrichment in their environment. I am still trying in regards to eels. Yours may benefit from occasional live feedings, as they could eat ghost shrimp or fiddler crabs, I suggest these as they are less expensive than a saltwater choice of crabs or shrimp, and unless it is an eel species tank, feeding live fish to fang tooth eels is a big risk in a community tank. The goldspotted may be still getting stimulated because some of your fish may be enticing him. Having dither fish in eel tanks sometimes help, as they try and catch and eat them. I'm in the same dilemma with my tessa and am considering a couple of triggers for him to wrestle with; my last fang tooth, a jeweled, was always out and about, because he had a niger as his nemesis, and they were always wrestling. I am also considering some dither fish like mollies or maybe some damsels, but damsels aren't as cheap as they used to be.
You make good points they probably need some stimulation. It would need to be fiddlers as I know how effective the wrasse are at hunting ghost shrimp. Also I'll restart with food burying.
Possibly. Obviously the cheetah preserve did that especially with the rehab ones so I feel stupid not thinking that when it came to the eels.Was it you I was talking to about working with wild land animals, we used to hide food and suspend it in trees and such for them to "hunt" for it. We would give some of cats pumpkins to chase around and batter into pieces. Some of our cats would bond with humans so we enriched them with human interaction. The tigers loved to swim and even though not water cats; we had a male lion that also loved to swim. A dirty secret of keeping wild animals in captivity, as they lose their natural instincts, it lessens their lifespan.
I miss a bood pumpkin. Those were fun to make.
