Those Parotocincluses...

While I did take some time off from the 120g, I can't say the same for the ADA 60-P.  If you remember, back in October I acquired some Parotocinclus eppelyi, or at least that's what they were labeled. Well, as it turned out, they were actually Parotocinclus sp 'Peru' sometimes known as P. leticia. I've had them in a 15g in my basement since October.

Well, I decided to move them up to the 60-P:

 

In preparation for their transition, I tested all water parameters. I transferred an Otocinclus affiinis into the tank to make sure it was safe. He made the transition easily.  I then drip acclimated them for 12 hours.

Sadly, they did not survive past 48 hours in the tank. Unexplained. The Oto, plus 3 others, are still fine.
