I put 7 white cloud in the axie tank, by day two there was only 6
The fish are remarkably smart (i suppose when your life is on the line.....) when the light is on (and the axies hide) the fish swim low and forage the lower part of tank. When the light is out the fish shoot straight up the top of the tank and stay out of the way (even when the axies are still hiding!)
They leave the gills alone (avoid the axies altogether actually)
My minnows have not bred. I'm not sure if it's the temp of the tank (chilled to 18 c) or if they have then they have eaten the eggs / offspring. Having said that, i have a "breeder tank that is heated and supposedly ideal for breeding minnows and i havent had any babies there either!
In 8-9 months of having minnows i have only had one baby - yes, one - and that only appeared in some java moss i had seperated into another container - so i suspect my minnows eat the eggs & babies.
Apparently, i'm the worlds worst minnow breeder
I cant breed the second easiest fish to breed! i'm going to try guppies next which are supposedly even easier, but i'm not holding my breath
Anyways, in answer to your questions - yes, minnows are a peaceful little fish, IMHO a good tank mate for axies (if you dont mind them being eaten every now and again) and they are actually a colourful, active fish to watch - i like them.
