Hello everyone,
I am researching on genetics with neotropical cichlids, and would like to separate species (I am grouping by genus) according to feeding behavior.
Feeding behavior I refer to the term used by some authors (Reference below along with more examples -see attached image-) to classify groups such as Geophagus, Satanoperca, Gymnogeophagus (for example) as Sifters; and Cichla, Astronotus, Cichlasoma, Crenicichla as Non-sifters.
Basically, if the fish feeds at the bottom, "sifting" the sediment for food, it will be defined as Sifter. If it feeds on the water column, it will be set to Non-sifter.
It would help me a lot if the answer was accompanied by an explanation and, if possible, images or scientific articles. But of course, all help will be welcome!
Obviously, the author of any help (as well as this forum) will be welcomed in the acknowledgements of my work.

Sifter Examples:
Satanoperca daemon
'Geophagus' brasiliensis

Thorichthys ellioti

Non-sifters Examples:

Amatitlania siquia
Hypsophrys nematopus
Mesonauta egregius
