first fish is a turqouise(spell)..red turq, and the second fish is a colbalt. i may be wrong but i stick with the old school strains...too many strains in the market that can also be confusing for veteran discus owners lol
oh and its really hard to tell sex until you actually see em breed, but if i would have to guess the colbalt is a male
The more solid colored fish is a brilliant/cobalt. The 2nd fish is a turquoise (red turquoise?). And yes, it is very hard to sex them with any degree of accuracy.
