Is this an altum??

I rec'd 12 of these today from Somethingsphishy; I purchased them as altums, the owner insists that they are but they sure don't look like altums to me. Your input is appreciated -perhaps I can convince Keith (the owner) that the 'altums' he sold me aren't altums

peruvian altums: not true altums, but very similar looking scalares, 99% positive

this little graphic shows how true altums' mouths differ from scalares.

Yea, somethings phishy all right, totally different fish from what is pictured on the site. Not a bad looking angel at all, I've always liked silvers with a bit of rust color to the crown, but it's not an altum.

I agree. To give the benefit of doubt to the dealer, the common name "Peruvian Altum" may be the confusion. This is, as was mentioned earlier, just a variant of the P. scalare species, not P. altum.

I do wish common names would fall into non-use.

You might find more info in our profiles, as both species are included with photos. Knowing the oprigin of the so-called "altums" might help to convince the dealer, since the true altum is wild caught and has a specific range as given in the profile.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
