Andy,
You are very fortunate
with the spawning but if I were you I would remove the other occupants and
maintain this tank as a species tank, gradually reducing the pH.
I would have thought for Regani your pH 7.8 was too high, just goes to show
how flexible species can be. Should this not be in the range of pH 5.5
- 6.0 as mentioned by Vinny. At present I am using his guidlines in
setting up a tank for the arrival of 3 pairs of wild Cr.Regani
Santarem.
Best of
luck,
Helen
Hey...shows how much I know! :-)
Congratulations Andy!
Ummm C. regani spawning at pH 7.8 is a bit unusual but
like I said in one of my previous posts, I find they are more influenced to
spawn by the amount of live food present than anything else. Of course, a
compatible pair and clean water helps. C. regani is found almost
through out Brazil except the east coast and thus are found sometimes in
water that is occasionally neutral or even slightly alkaline. They are
not strictly blackwater fish. I am not surprised that they spawned in
alkaline water but I am that the eggs hatched. Also, Andy's fish are
F2 - perhaps that had something to do with it.
