The tank is heavily planted with 2 Otos and 1 male Betta. I can remove these if necessary.


My main goal is to have a tank of these little Goby's, and I'm having a hard time finding information on how many is too many.


Thanks

I think the formula is roughly 1 inch of slender body fish per gallon. This isn't an exact science, just a guidline to keep your fish comfortable. Oto's get about 2". Betta about 3". Peacock Gudgeons about 2". So maybe 2 or 3 depending on how well you have the tank filtrated and how much maintenance you do. Here's a link I used to figure out how many fish I can fit in my tank. You can input your specific info and it will give you an estimate. If you don't find your filter you can input a similar filter.

Tateurndina ocellicauda (Peacock Goby) ? Seriously Fish

Here is some info about how social (or not) they might be.
It sounds like if there is enough space for them to get away from each other if needed, then perhaps 2 pair might work in your tank.

They have a body shape similar to a betta, so there might be a problem there. I say maybe 3 along with a little clean-up crew. I have 1 right now and I am getting a second one for my 15 column. Awesome fish.

I have not owned them, but I am seriously considering them. In the research I've done the advice seams to be that a trio of 2 females and 1 male works well. I've heard that in a M/F pair the male can pester the female to the point it stresses her.
