Poor blue gouramis

[shawn123]

so i got 2 blue gouramis, already have 2 gold ones, had them for a bit now, anyways it seems like one of the blue gouramis may have been picked on so much by the golds that one morning i woke up and he was dead , but it seems like the other blue one they have taken too and he is cool with them, so now i have 2 gold and 1 blue, is this normal? My gold gouramis have been great with my other fish, havent even bothered with them.
