the lower fish in this picture ( I have 2 ), that appears to be thriving... Mrs. calls them dragons... have not been visible lately... but this morning the larger one, that I believe is the one in this older picture, came out for just a short time... in this picture appears kind of camouflage ... but this morning, it was off the charts colorful... oranges, reds and golds... I did't get a picture of it, but it was on the pagoda roof like this for a few seconds... I only have 2 of them in this tank, as they are a larger variety, and it is now 10-15% larger than this picture... as far as I know, most of these are egg scatterers, but again, there just isn't much known about these...
