My peacock gobies have layed eggs for the 5th time. Every night I go to sleep w/the male fanning them. By morning they have all been eaten. This time I scraped them off the glass (surprisingly, I got them all) & put them in a breeder net. I had it hooked on the same tank they were layed in & the rainbows were sucking them through the net! I moved them into a FW puffer tank. I have them hanging opposite from the overflow of my filter. I hatched several corys in the same way. I'll update you when they hatch.
