I will try to answer this for you
As you know, axolotl produce a lot of eggs. If you are successful, you could potentially be in the situation of having 100's of larvae, that all need feeding. It's not always easy to provide enough micro food at the start. This could lead to many dying from starvation. As they get older and onto slightly larger food, you may find that they eat the smaller ones..which to be honest is quite natural. Raising 100's of larvae can be expensive and time consuming. Having many larvae at a time also needs regular water changes, small larvae in small tubs grow into big larvae needing bigger tubs...space may become an issue.
Re-homing lots of bigger larvae , as in with all their arms and legs can also at times be difficult. Selling them just hatched is tricky as they can be more sensitive to changes and movement and the buyer must have a food source available, many can die.
If you get to the stage where you have maybe 50 small axolotl, that you have successfully fed and raised and most still have their limbs. Then you will need to find them new homes. This is the bit I hate most
Who do you give/ sell them too? Can you trust them to look after them as well as you have? Do you resort to sending them to a pet shop, unless its a good one, they may be doomed.
Now, you may well be in the position that you can easily provide them with all they need to reach a time to go to a new home. But many people don't realise the implications of raising lots of larvae and it can be a grim time. I would personally cull eggs when they re laid. They can be left in the adults tank, where they will most likely be eaten..all perfectly natural. Any larvae that are then seen could be rescued and raised...as long as you can provide food ( I'll say at least twice a day).. this is a method I use. Eggs can also be easily re-homed. You can advertise them here in the 'For Sale' section....selling them gives you the chance to maybe get the adults a treat
I personally would hate to cull lots of larvae, in fact I loathe culling any larvae that are deformed or sick, but it is necessary.
The person who responded to you on Kijiji was insensitive and arrogant to feel the need to respond in such a way. Wanting to raise the eggs is understandable, I did when I first had axolotl eggs
However I was advised through the forum not to. Here is one of my earliest posts :-
