OK, here is my update, I lost to guppys during a cycling, but 2 others on the next day became very active, and starts eating.
Yesterday morning I transferred my C. paleatus trio to this cycled tank, and within 3 hours I found around 120 eggs ... I was a little surprised with perfect timing, so I went back and found around 40 eggs in original tank as well (I am sure there was more, I have male egg eater :(
Can I leave eggs in new (5.5Gal) tank, or should I collected them in to a smaller container with air stone?
I have very nice water flow from Hang-On filter, also I have internal sponge filter.

Thanks,
Aram
