Over a month ago i bought two Hydrolycus tatauaia.
I had read about these fishes for a while when i finally found them on a Stock list, at a lokal store.
I keep them in two seperate tanks, both With a very high flowrate and low lighting. The aquariums are about 800 liters, and the tankmates are some Pseudacanthicus leopardus, Geophagus proximus, Geophagus altifrons, and two small species of stingrays. pH is constant stabile at 7,2, and temperature is about 25-26 degrees celsius. The tapwater here is very soft, so i add a bit of magnesium and kalsum at every waterchange (once or twise pr week – 50-60% to keep nitrates under 25 mg/l). I also use Aquasafe for some of my more sensitive fishes (i consider tatauaia one of them) at waterchanges, to help promote the production of mucus when the fishes get a bit stressed.

And now they FINALLY took some Food!
Was getting a bit worried at this point, and so yesterday i spotted one of my smaller balance jigs that hangs on my note-Board…. why have i not tought of that before!!
I stripped off the plastic Fish imitation, bended out the hook, and clipped of the Sharp end. Then i peeled some market shrimp, chopped off the tail end, and attached it to the jig.
Worked out perfectly! They both striket at the short moment i was holding the bait still, making only a minor vibration movement, in between the rapid jerking.
Next step is to insert a small Hikari Carnivore pellet inside the shrimp meat, to make sure they get as mutch quality nutrients as possible.
I never give any of my predatory fishes live Fish as Food for several reasons. Even though i knew these fishes are known for bein hard to get on dead Foods – this was never a option for me. And luckily i got them to eat after all, so im very happy about that.
