Well the primary reason is because they're not native to Thai waters and I was hoping to accumulate information on those that I can possibly follow up with in their natural environment to continue studying, secondly, they are they most expensive and not necessarily needed for the study, and thirdly, the one I currently have at least is VERY sedentary which makes me wonder if it has to do with the true nature of the species or handling/care from the seller (there is only one source I know of for that species and if the seller has a starved or mishandled batch, I'd prefer not to invest significantly more money to determine that). I don't like casting blame on the sellers though and besides, the primary reason I stated is enough to justify not buying additional individuals.
Have you considered that they could be attracted by the nitrogen that is being infused by the air stone? Some nitrifying bacteria transform no3 into n2 gas, maybe they looking for nitrifying bacteria.
That's something I haven't considered but why would they be seeking out the Nitrogen? Do you have an idea what function that would serve them?
It’s more of a random thought, not based on any real evidence.
That's very interesting but I doubt that's the case (although I can't disprove it) because in the wild I don't see how an airstone would be replicated naturally. Plus when I turn it off, (I've been keeping the airpump off) they stay on the rocks and at the bottom of the tank.
I’ll try and make a video for you later
As promised
I feel I've learned a good deal about their feeding behaviors and food preferences, preferences regarding water quality, believe that they can somehow sense oxygen concentrations and prefer highly oxygenated water based upon behaviors I've observed, feeding differences among two species in the genus, among other things which I'll compile in my report.
