Corvina, powder blue dwarfs and blue gouramis are different. The blues get big, well, 4+", lol. The dwarfs stay around 2"-2.5" long.
Thank you all for the information. I suppose powder blues may just be a bad choice at this time. As much as we love them, we may have to wait for another male.
The funny thing is, every site that sells them claims them to be a very hardy fish, able to adapt to various water conditions and easy fish to keep. Like I was saying, the regular dwarf *male, red/blue* has survived slendidly. He is truly a beautiful fish, his colors are incredibly vivid. The only thing is, he's aggresive, well, he's aggresive toward other males. Also, sometimes he will chase off a tetra if it gets too close. Would anyone recommend we move him back into the big tank? At this time, we have two females in there. I know he won't mess with the corydoras, the zebra danios are too ellusive, and the two killis are tough fish in thier own right. My only concern would be if he became aggresive with the two females. I would think he'd be happy to have two little girl friends. What advice would you all have on that?
