Fishes part III
As I was sharing, the 3rd batch of eggs was layed on Thursday. This time round, there were ALOT of eggs layed. I didn't know Discus fishes are so productive. Read from the web that apparently they can lay eggs weekly for consecutive 11 times! That is one cycle. In the life-time of the fish, it can have two of such cycles (meaning they will lay eggs 22 times)!
My dad decided not to put the wire gauze to see if the chances of the eggs developing into frys are higher. We tried not to alarm the fishes, so we had to creep slowly towards the tank when we need to satisfy our curiosity (the wonder of nature, I now can also sit in front of the tank and stare for hours!). Luckily the fishes did not eat up the eggs! Also, thank goodness for my super zoom camera! I actually took these photos about 1 metre away from the tank.
I think this time round we may be able to get some of the eggs hatched as we noticed that some of the eggs turned 'black', which is a sign that the eggs are fertilized and developing into frys! Also, I noticed the parent fish will fan the eggs very vigorously, especially towards the 'blacken eggs', such that they actually fall to the 'catchment' area of the breeding cone.
Then the parent fish will pick up the fallen egg and try to stick back to the cone (see picture below, I managed to capture a photo of the fish doing it. The blackish dot in between the fish's mouth and cone is the egg). So far, none was successfully stuck back onto the cone. Nevertheless, I saw the 'blacken' eggs wiggling on the catchment area once every few seconds!! So exciting! I counted about 17 of them so far!
After the frys break out of their eggs, they will get hungry and latch themselves onto the parent fishes' body to receive nutrients! Will try to capture a picture of it to share!
