hi
Not much information that I can give you; but, I hope this little amount may be of some help.
I once, got some
to spawn I had eggs but only three hatched, and the fry subsequently died within 24hrs. (so I class this as a failure to spawn) .
The tank set up was 12"x10"x10", sand substrate with an air powered internal sponge filter. To which I added an egg trap that had nylon wool intertwined with the mesh. the eggs were laid in the night-time hours. I remember feeding the adults on blood worms, white worms and small granula commercial feed.
PS: Sorry , I cant remember water measurement and my notes went astray some time ago .
