I really can't tell from that pic - it's blurred, wrong way up and has a blue cast. But it doesn't look much like a severum from what I can see there..... looks too long and slender, but that may be camera angle etc. Can you get a better pic?
Here are a couple of shots of my Rotkeil Severums as juveniles and as adults to compare. Green/Gold/Red sevs will look a little different in clolour, but basic shape and markings will be the same.
Word of warning Nathan....juveniles of the ordinary green and turquoise severums look much the same and the red head/neck that gives the Rotkeil its name doesn't develop untol theyre 3 or more inches long. Rotkeils are more sought after and more expensive than other strains of Heros so will usually be clearly labelled.
Care needs are a minimum 120cm x 45cm x45cm tank, approximately 250 litres, soft water gH up to 8 and pH 6-7, temperature 22-29c. They can be kept with other SA cichlids, larger tetras, cories, plecs and other robust fish who share their requirements.
As cichlids go, they're pretty peaceful (although a single male may get nasty). They grow quickly to 8-10 inches (20-30cms). They breed easily and are excellent parents, but if you wanted to breed them you'd either need to buy a group of juvies and let a pair form naturally or by an adult mated pair.
There's not much point planting a tank for severums as they will eat just about any plant in the tank. I'm tryin g tougher plants now like Java Fern, Anubias and Bolbitis as they may leave these alone.
