I understand why you think so, from the look of the way the spots are on what you can see on the last picture, – that in my opinion could look like deissneri – BUT, – this really does not mean that it is, – you have to put it together with the rest, especially the colours in the tail and there are other species that might look the same. You can see on my picture, – this is not a deissneri, – although it has similar type patterns in the unpaired fins as yours. This was identified as sp. Sentang, – and yet still not certain about that anyway. Very beautiful fish though, which unfortunately I dont have anymore now.
Is there red in the tail ? It looks like that in the second picture.
I would agree with Christian, its still likely to be a bintan type fish, or the others he mentions.
