What are 'roiboides'?

Please remember, this is an international forum, most people don't come from the USA (as I do) and therefore Latin names are highly preferred

Roeboides. Great fish but they are scale eaters and they can eat cichlid's fins if they are in large number.
Bas, they are from mexico to argentina. Have you seen it (microlepis?) in uruguay? There was some in Felipe's tank.

Ciao Enrico

Sorry typo error. Auto spell correct on apple products :) I meant Roeboides guatemalensis

Do you have any further info on their requirements? How are they with livebearers? So far they are good with my cichlids as i have only six tetras. Does this variety also eat scales? Or is it something they only do in large groups?

Adult (15-16 cm.) can eat livebearers (if they attack in group) or usually they eat only fins and scales if the attack is from a single fish. I've met them from panama (rio chagres) to mexico (near tapachula), they live with livebearers but in nature it's not like in aquarium. They can eat insect larvae and small crustacea too. Reproduction is like other characids, astyanax for example.

Thanks Ciao,

do you know how to distinguish between male and female? Also, I have fed them Mysis shrimp and Brine Shrimp which they seem to like, but they are not to keen on Spirulina flake or tetraPro discs. (Maybe because they are wild?)

Yes they prefear shrimps and larvae. External dimorphism it's difficult to see but you can see the different genital papilla in male and female.
My name is Enrico. Ciao in italian means "Hi".

I remember wrong. I've seen the photo I took in uruguay and there are only Charax stenopterus in Felipe's tank.

Yes but very difficult to do if they are wild.

If you buy and cook fish you can use scales and fins. This is a genus all lepidophage.

I would like to go in December or January next. However I don't want to go alone, but with an European group. German, Italian, Dutch, Swedisch is all OK

Enrico,

in your experience, have any of these tetras ever turned on 'each other' and killed each other or began to eat each other. I presumre from your description and what Ive seen they are very capable of this.

Imo they are more aggresive than astyanax
