I need some help identifying my 2 baby severums.
I saw them at my LFS a week ago and couldn't resist, especially since this was the first time i've seen them there. Was wondering what kind of severums they are since they were just labeled as severum.

Looks like a standard 'green severum' to me. These have been in the hobby a long time, can vary some, and likely have mixed genetics vs. wild populations, or versus a "Heros species x " of known provenance.

That said, several Heros types can resemble each other at that size, but you'd expect a knowledgeable store to label them as such if they were something less common. Standard 'green severums' are still nice fish as adults. :)

Alrighty, thanks for the info!

My LFS usually have a truckload of information about every type of fish they have, but somehow they manage to mislabel them all the time haha

Who knows, then-- he does have some nice red on him, rotkeils have become common, look nearly ideintical to greens at that size, except having 8 bars, but occasionally they have an extra bar or half bar, so time will tell. Some green sevs can also have a lot of red in their fins.

The orange starting behind the gill and the anal fin color makes me think rotkeil, but there are a lot of rotkeil crosses out there so it may or may not end up with all the characteristics of one.

Unfortunately tank and farm bred Heros are a mess genetically, unless you get them from someone who’s kept them pure.

We'll see! I really like watching my fish develop over time, must be one of the most fun things in the hobby

My gut feeling is telling me it's a cross between a rotkeil and a green sev, but this is the first time i'm keeping sevs so I guess my gut feeling isn't that dependable. Really curious how they'll turn out

Same here, part of the fun, though not everyone has that kind of patience.

Yes, possible. Some standard domestic green severums can also get a bit of orange on the face (as already mentioned, garden variety 'green severums' probably have mixed genetics), so I'd want to see more development toward rotkeil to convince me, but possible. Like you say, wait and see.

There's a good bit of diversity in (current) H. efasciatus wild populations, some with varying patterns of red (not to mention H. severus, liberifer or other Heros with red/orange/maroon). But as it is, the Heros genus is likely due for some house cleaning, some current "efasciatus" may not stay that way, which could muddy up the 'green severum' waters even more... or one can simply accept them for what they are, a legacy domestic fish with a cloudy, melting pot history, especially by today's standards of paying attention to catch locations, etc, but still a nice fish... :)

Its a waiting game now, theyre pretty shy so they tend to be in the back of the aquarium. I noticed that they start to develop a blue-ish hue on their cheeks. I'd post a pic but its hard to make one since theyre hiding. And I still have to install the proper lights, so they'll have to make do with a small desk light right now haha

Rotkeils faces have blue (or greenish blue) in them, female rotkeils have blue faces without line makrings. But some greens (and others) can also have blue in the face and/or on the body, which shows in some moods more than others--

A Jim Cummings video-- Jim's probably one of the guys people are thinking of when they mention members they miss around here who have gone on to facebook, etc.
