Lol, sorry about the strange question. Anyway here is the situation, I have a 50 gallon tank and have had Discus now for about a month. I got the fish from a local recommended breeder, he told me to get 6 young fish so that they would shoal. Anyway, they did not eat well for the 1st week and after 8 days, 1 died.
Of the 5 that are left I want you to look at the colour of 1 of them, he/she seems to have a blueish/grey tint, doesn't feed as well as the others, but doesn't seem to be being bullied. Have a look at the pics below and tell me what you think:
Here he is with one of the others:
Here is one of him on his own but the flash went off:
