Just wondering out loud. I have noticed a few of my Pseudomugil fry seem
to have difficulty swimming horizontally. They seem to be swimming head up
and tail down. Is this like the swim bladder disroder that is often
described by Killifish breeders? Water poblem? embryonic development
problem? Genetic disorder? Pathogenic Disease? I kinda don't think that
it is the last, but the fry don't seem to get over it. I haven't seen it
on melanotonaids. I have noticed it on Ps. furcata and Ps. conniea. I
do get a small percentage of deformities (scrunched bodies ala ballon
mollies, crooked spine, etc) that may be a result of Ca deffieincies or
inbreeding (I don't think these species have been recollected inrecent
history).

Any ideas?

BTW anyone on the list in Honolulu or Hawaii that wants Ps. furcata let me
know I will have a bunch allmost ready soon.

TIA,

MTF
