I think our fish are constantly adjusting to the conditions we offer
them in captivity, and we're blindly selecting for more than just
colour. I had coeleste Mounana or Mouana (spelling error - I don't have
my notes) until 1998, and it was easy to breed in my pH 7.4, 140 ppm
city tapwater. I also had the GBG population spawning under exactly the
My Titi population are a lot more difficult for me, but I am starting to
get 20% hatches (only over the past two weeks - 2 fry!). I keep them in
50 percent rainwater. I had the CMBB population and never got a viable
egg from them - a killer because they were so beautiful.
I don't know why the populations were easier, but I have seen similar
things with ocellatum. With the samples we keep, usually starting with
one or two pairs, the pattern could be pure luck for all we know. Still,
if I could find the Mounana fish again, I'd try them in tapwater, while
if I were incredibly lucky and found the CMBB Massenga coeleste, I'd go
with much softer conditions to start.
You know, this is pure speculation, but I kept elberti Diang for many
years, in tapwater. They did very well, generation after generation. I
changed my set-up and had better access to rainwater. I spawned the
Diang in really soft water and got a lot more fry. Whether I had messed
up with that is a mystery, as inbreeding could also have kicked in, but
those fish became impossible for me. I could never get consistent fry
from that softwater batch, and have now lost the fish. Coincidence?
Possibly. Probably. But you have to wonder.
