Observation: One oto is huge and the other is small.

Both of my Otos were the same size when I got them, but now one is huge!!

Somewhere, somebody wrote, "a happy otos is a full oto." When you look at the belly of an oto who has been eating well, it looks full and round like a green pea.

Well obviously on of my guys eats much more than the other. No only is he probably 3 time the mass, but his stomach is full and probably the size of a lima bean!

Are you positive that both of them were oto's?

 

[gfink]

:? Ummm....I guess. I got them on the same day out of the same tank at Petsmart.

Are you thinking that one is something else like a SAE? Tonight I will try to scrutinize the stripes on them.

 

[greenmaji]

yes.. thats the first thing that crossed my mind.. the last time I was in a LFS I saw a bunch of little fish they just called algae eaters.. there was at least 4 different patterns on them.. good luck

Awesome! I may have a mystery fish!

Update: I checked out my otos and they both look exactly the same (an neither one looks like a SAE) One of them is just much bigger and a better eater. Maybe the little guy is stressed?

Anyways, I picked up a third oto to kick up the cleaning a bit, and it might also reduce stress since they like to be in groups.

Thoses otos are fun to watch!

I have a really large oto and two smaller ones. I believe that the females are generally larger than the males. So I would say you picked up a male and female.

Plus it's quite normal for fish to grow at different rates
