I got this today from Lars Jamne regarding the first picture:

"Seems to be pretty young still, just keep an eye on it and see how the colours develops. Mostly mine have been real black, but some here and there have been less black before they got adult size."

I'll wait and see...

OK. I got this from Lars Jamne today:

"These wants a higher temperature and a more meaty diet than the common Ancistrus. I keep mine i pH 6, 28-29 Celsius and feed them Repashy Superfoods (60-70% meat variants and green the rest)..."

Thanks for your help. Yes, I had read that, but the feeding portion of this entry is the stock answer regarding Ancistrus generally. Some species of Ancistrus require more meaty diets (which ones?). Additionally, mine aren't showing much interest in what the stock answer suggests and thus I'm ...

I'm a new keeper of some wild caught L107/L184 Brilliant Bristlenose.
