Re: Rivulus cryptocallus
I too bought R cryptocallus (a trio) recently, at the BKA Manchester Group
auction. I was home within an hour and had the fish in the tank in another
by which time there were at least a doz eggs in the bag.Currently they are
set up in a 2'x1'x1' tank with a mixture of rain water which I collect and
tap water(which here is quite soft). I have not tested the hardness but pH
is about neutral.A bare tank except for 3 mops ;two floating & one on the
bottom for cover.As I'm in the process of moving house care has been
minimalist so far-plenty of live food & little diturbance .The fish
temselves are about 5/6cm the females a little larger than the male but all
young fish just maturing.The eggs, which are comming steadily; are large,
easy to see and handle.The first one hatched today,10 days after laying,
having been water incubated at 74C.The first food will be the micro
population of my water butt.These are the first R.sp I have kept for 20
years but if they follow the pattern of the large sp. I kept then (holmaei &
hartii) they should be able to take small daphnia & the like very quickly.
