I'd agree either a rottie or rottie/green cross.

It looks small though so should colour up with some good water and food. Maybe try a water change with rain water instead of out of the tap... Sometimes I have found this to help.

Also feeding a couple of live food treats might help small pet shop crickets or locus.

Any dither fish around?

Its a good 6 inches long. I was actually looking at some silver dollars at the weekend, I may get some saturday. No other dithers. The whole tank looks empty at times apart from my oscar. Dats are normally hidden, bushfish is out now and again, polys are amongst the wood. I need some more life in there. I have a dwarf giraffe cat, 2 spangled perch and a pink tail chalceus growing out but they're not ready yet. Ill maybe see about some live too.

In that case I'm going to say its just a stressed rotkeil severum as they carry quite similar underlying markings and traits as the green severums.

Just check the water should be looking towards. Probably already know this.
72 - 85f
6 -7.5ph
5-10 hardness although I tend to find if they are tank breed this doesn't matter to much.

Maybe a couple of females?

I do want another, but im having trouble finding one big enough at the moment. How do you sex them other than the facial markings?

Oh, ph and temp fit with what you suggest. No clue about hardness though.

My yellow severum is female you can see the difference in the face markings and also the length of the fin trails. As you can see the female fins are a lot smaller.

Going by that then id be very confident mine is male. Ill be on the lookout for bigger females. I could order one easily enough but can't get the time off work for the next few weeks to be home for delivery.

Severums are fine with ph anywhere in the 7s and probably higher and a range of hardness ime. Mine, including a wild rotkeil, have been kept in hardness typically @ 12-14 GH and KH. Other places I lived had softer water.

First impression for me was rotkeil also. IME sevs are comfortable in water temps in mid 70s- lower mid 80s. Much cooler than mid 70s stresses them ime, at least that was definitely true with my wild rotkeil.

Other than being faded, he looks ok imo, nothing obviously wrong. Have you had him long? Could still be nervous if he's new in the tank. Though I wonder why other fish are not out much, which could be a number of things, even lights too bright.

He's been in that tank since February when I upgraded to the 180. I think I have a group of what are just potentially shy fish. The lights are actually not that bright. I like the more subdued look, my 65 is much brighter. Maybe some dithers would help

Haven't kept them myself but I've heard of dats going both ways, some shy, some not. Some tanks it seems like other fish take their cue from the shyest fish in the tank, spook easy, etc., in which case dithers can make a big difference ime.
