Everything you ever wanted to say about "Zebra luvin", but didn't because you thought everyone would take the mickey! Plus general topics for discussion including everything from what you feed them to your personal experiences.
keep the water quality as perfect as possible, fry are very sensitive to water changes and water parameters being off.. also the sponge lets u feed them flake food crushed up, sticks to the filter and allows teh fry to cling onto the filter and eat or just hang out too!!.. main thing is keeping their fry trap clean like the filteration on ur main tank would do. just a mini filter system for ur fry.. hope this answers ur questions.
The sponge is to cover a big hole on the side of the trap, so that the young zebras don't get out.
A trap is like a mini tank inside a tank, the water enters the trap by a sponge filter and leaves through the hole in the side which the sponge covers.
