I have three black widows and am wondering about their ages and sex.
All same size
#1 Black fins
#2 Grey fins
#3 Virtually clear fins
Is the colour of the fins an indication of age and if so in which way does it work?
Also other than plump belly is there any other way to determin the sex of one?
Also my #1 fish's fins have become alot blacker since 8 hours ago when it was first introduced to the tank
