I got 12 cherries (one with eggs) about 1 month ago and I put them in my 75 gallon tank. I have heard that some people have found them in their filter so I was on the look out. Well I did find some babies in my tank but none in my filter the first go around. Well that was two weeks ago. I checked yesterday and I saw a little guy swimming around the filters bottom (eheim 2026). I cracked that baby open and found 7 babies swimming down their!! All different sizes. The weird thing is I never saw a female with eggs.
Cherries have got to be the guppies of the shrimp world
