Rainbow Fish Sex ID

[Josie12012]

Hello! I’m hoping someone can help me determine the sex of my 4 rainbow fish, I’m fairly sure I know but wanted to see what someone more experienced thought. I’ve had all four for about 2 months now. I plan to get some more for my 90 gallon tank but would like to make sure the sex of these ones first! Thank you all so much! I’ve attached 4 photos below.

Please do not post the same thing in different sections of the forum. Posting once would be better.

Yes... sorry, it took me a minute to figure out how to post to a particular forum.. when I realized it posted to a forum I didn’t believe was appropriate I tried to post it where I thought it would be best. Anyways, when I finally found the right one, I didn’t see an option to delete the others. I’m obviously new on here, sorry!

They all look like males to me. However, they are different species of rainbowfish. The one in the first picture is probably young (Red Irian?), and is not in great shape. Is there aggression among them?

thank you so much for responding. I was told when purchasing them 3 males and the bottom left or 3rd photo was a female. However, I agree with you, I’m starting to think I have all males due to such bright colors! Interested still to hear what others think..

The red one was the last of its kind in the store and looked the same when I bought him.. I’m hoping I can get him in better shape. Thankfully no aggression, they all peacefully swim together!

That's correct. 3rd from left is a female M. boesemani.

Not sure about the first, maybe male hybrid G. incisus? 2nd is male M. boesemani. 4th is male M. herbertaxelrodi.

Hey there,

I agree with the above that they’re likely all males. The first is a Red Iranian (and looks like he’s in pretty rough shape), the second and third are Boesmani Rainbows, and the fourth is an Axelrodi (yellow) rainbow fish.

They are all Melanotaenia Rainbows.

mid you’re going to introduce more, I would definitely add females, and hopefully you have the room in your tank to add two females for every male.

Good Luck!

Well, first, they're not all Melanotaenia. The Red Irian (not Iranian, common error) is Glossolepis incisus. The genus is endemic to New Guinea. And the third image is a female boesemani, as several posters have pointed out.

Well poop. I’m a little rusty I suppose. Been a few years since I kept freshwater fish
