Description:
|
Initial spawn was not seen and the eggs were only visible at 2 1/2 weeks.
At this stage, they were balls of a cream/grey colour with a large single eye visible.
About half of the eggs were attached to each other, the remainder were loose.

Location:
|
Spat out by the male into a net and my hand.

Other Details:

The eggs were artificially incubated for the last few days 21/17/2013 - 2/22/2013.
This involved putting the eggs into a glass conical flask (1000ml) filled with tank water.
This was then placed in a hatching tank, with a sponge filter, heater and a water pump.
The water level of the hatching tank is such that there is a 3-5mm fall from the lip of the flask to the tank.
The water pump has a long screened input pipe, to discourage input suction of fry (it is about 12" long).
The pump then is piped to the top of the flask and the water directed into the flask, so that the eggs are in continuious motion. They are not really tumbling, just moving.
The pump also has a bypass tap, so that the water flow into the flask can be tuned to a low enough setting.
Im using a 500L/h pump, feeding two seperate flasks of eggs, plus the bypass valve.
