Hello and welcome~
Here’s a good place to start for you:
That will help you know what genes can have issues and what you may want to avoid.
Personally, because you’re starting with a blue eye Lucy I would tend avoid the following genes:
Pied
Albino
Lesser/butter
They won’t cause any major issues like kinking, but BEL genes(not just lesser) likes to make small eyes in the pied and albinos and super lesser/butter can make big eyes.
I have seen some single BEL gene albino combos with small eyes, but usually for pied and albino the issues will be with 2 BEL genes
Otherwise… I think the most import thing is to watch some videos on yt or browse the market for animals that YOU want to produce.
Personally I have BEL, Hypo and Pied projects for me right now… Because I think they’re neat.
And as cmills mentioned, the market is super saturated right now so unless you’re prepared to keep the babies a while or sell for cheap… I’d avoid it. Also keep in mind possible vet visits and expenses as well.
