Would it then be advisable with these fish Byron to have these "night lights" screw in bulbs to observe them? I mean for "normal" people that already have hard times training their dog how to sit, much less train a fish to come out from the hiding place (thou remembering my dwarf frogs used to grow very used to the offer of bloodworms too). The sound real interesting...You don't by chance have a long post or a outside linked article where I can read up more about them would you? Their behavior sounds interesting to me...
There's some info on Planet Catfish here: Centromochlus perugiae • Auchenipteridae • Cat-eLog • PlanetCatfish
though I don't know that I would agree with this fish being a surface feeder. After dark with a flashlight I do see them at all levels of the tank, so might be. The reproductive method indicated for this fish is interesting, and if you follow the link to shane's world article it is detailed with photos.
I do not advocate "night lights" in freshwater aquaria. The fish and plants require 10 hours of absolute darkness, no room lights, no moonlight, nothing. This is what they are used to by evolution; the moon does not shine through the forest canopy. And studies have identified plant growth problems without total darkness.
Fish that are programmed to swim in darkness need just that, darkness. It is unfortunate that it makes viewing difficult, but it is very easy to train these fish. I have read of others doing this, and I didn't set out to, it just happened. I feed flake and tablets in the morning. In the late afternoon, I feed frozen bloodworms only because I have some wild caught fish that basically eat nothing else (my Poecilocharax weitzmanni in the 90g), so on alternate days the bloodworms to ensure they are getting something. And I feed the corydoras in the 115g as a treat. So, once I had found out where these woodcats were living (when introduced into the tank they disappeared, finding a tunnel in wood and staying there; I did the night flashlight routine just to find them), I squirted some bloodworms into the tunnels. They are clever; after only a couple of times of doing this, the next day at the same time, there they were, peeking out in anticipation.
