What type of rainbow?

[bruinsbro1997]

Looking at your pictures again, I think only your first one looks like an Australian rainbow. I have kept an australian, very nice and active fish, but need big tanks, around 55 gallons. I had a female, which was more slender and more blue/gray and hints of green in coloration.

Your second one in the pic...it kind of looks like this:

My first pic there shows the male on the left and the female on the right....these guys are still a bit immature but growing steadily. Both are colored nicely but the male is definitely greener with a more distinct black outline on his fins as well as deeper bodied. The next two pics are of my male alone....your slimmer ones could just be younger males too, but I would put my money on them being female...just have to watch and see When I first got the three I have they all look fairly alike coloring-wise except the male was slightly larger.

Of course, the general name of Melanotaenia fluviatilis can have different subspecies from what I have found on the web, dependent upon which creek or river they came from too - a real guessing game.

It really does look like M, fluviatilis. So hard to know if was caught in the wild or has been breed. The Murray Darling is such a huge River system it really is a guessing game to know where it came from.

There is now a much larger updated version of 'Rainbowfishes' by Adrain Tappin that just came out:

Rainbowfish Book

On page 272/3 there are some great pics and info on them.

Yeah they look just like my australians. They're dimmer Rainbows, but very active, fun fish.
