How old are your pair again???
How long have they been laying eggs????
They are about 2yrs old because I think I got them when they were about 6mons old.
They started laying eggs a 3 months ago this was batch #7.
Have you collected a sample to see if their still alive?
I have but some looked good and did not.
I guess I will need to get a new culture and start over with the Rotifiers. I
have been feeding mine the Rotigrow Plus stuff from Reed.
I use the L type Rotifers..... I purchase them from my LFS... BUT they purchase them from Reed Mariculture..
I feed them RG complete...
