I currently have 3 yellow labs in a 40 gallon tank with some other tank mates and i noticed that all three have eggspots on their anal fins now...is this a sign that their breeding or what?
Egg spots are often a sign of a male fish, but females can have them too so it's a fairly unreliable way of sexing them. How big are they now? Males will generally start breeding at about 2.5 inches, females a little smaller. Signs of breeding can only really be seen through behavior.
