Thanks, I'll give it a try.

I was just searching how to separate the same species in different tanks when I stumbled upon this topic. It would be cool to add this option, because, for example, now I want to add juveniles of the same species to another tank and also to mark the date when I got them, but the only thing I can do ...

Thanks,

Now when i look at it closer, i think you are right

I'm not sure which L-number is this Peckoltia, i presume??
