Day 29 (12)

Day 29 (12)

I have split the hatchlings into 5 tubs now as they were getting a bit bigger. They are now in 1 / 5 / 6 / 8 / 8

The tubs are a bit clearer so makes it easier for me to see the BBS moving about.

I had planned on putting them in the tubs relative to the size of the hatchlings but the things too damn quick to catch. Never seen something move so quick in my life, at least double the speed a platy fry is when born.

Some of the hatchlings are much bigger than the others, like my frogs these are facinating to watch them move about and try and eat some food.

Several of the bigger ones you can clearly see the blood vessels in the gills but its really hard to take pics of that. After watching them it seems they also use their gills to detect movement of live food.

Now they are bigger you can see inside their bodies, you can see its stomach and its poo tract. You can see the poo clearly in its tail and its anal cavity is near the end of its tail rather than near the body. On average the poo travels 4mm along the tail and then exits.

Four of them you can see the front legs forming, they are just below the gills and look like white and flop about so not rigidtity to them yet, and unless you knew what to look for you would just think it was part of the gill. Again impossible to photograph. (the front legs come first not the rear ones)

Here is pics of all 28 hatchlings
