interesting fish... but reading up on them also puts them out of my purchase range...

unexpectedly they like cooler water than the common Oto... and are typically even smaller... I thought about a couple tanks, that I could use another oto, but these guys like it cooler than Ivrun either tank, that I was considering, adding them to...

Sometimes when I read about fish, I feel like one of my nieces who really wanted a pony even though she lived in an apartment. It wouldn't have worked out. But she couldn't read yet.
That saves us, sometimes.

I'd love some a. d51 but i doubt anyone will import them in my lifetime. Some friends took a trip to Peru last month but they never left the city though they did comment on a nice transportation strike

"We keep all our fish at a temperature of 79 F"

"What is most important is that the water our fish are put in upon arrival have steady parameters, not that your water parameters match ours. "

So they have 3 degrees difference between "some" other oto's... Does it mean a death sentence at 80-82 ?

Oto's while they look like some loaches but, they are not. And I'm pretty confident that they will live at any temperature other oto's does.

It's my own opinion... But "steady parameters" includes temperature, in my mind. I wouldn't worry if the tank is not always maintaining over 80 all year long.

That would be a little high for many tropical fishes anyway.
