Here I am with a first set (separated in two parts to avoid seeing too many pictures at the same time) of pictures on which I need your insights.
I have taken them in a very nice small aquarium located in the french city of Lyon (center-east of France). The labelling system wasn't always accurate and I couldn't find these specie's name.
So here we go for the first part :
1/ That one was labelled as Apistogramma macmasteri
but I have doubts
That's it for the first part! In advance, thank you very much for any help you can provide.
Please, if you find the name of one of these species, could you precise its scientific name as I sometimes have trouble to find the translation for english names.
After identifications, I will definitely add some more pictures from this place.
