Sizes are 1= 9.5cm, 2= 7.5cm, 3= 8.5cm, 4= 8cm, 5= 9cm, 6= 8.5cm, 7= 6.5cm, 8= 7cm.
Number 7 has always caved from the day I got it but has no cheek odontodes as yet.
Number 5 has quite long cheek odontodes and pectoral odontodes.
The rest have little or no cheek odontodes.
I have had them from 4-5cm since October last year so the next 6mths or so should mature them up to be more definite in male/female traits.
I caught them for a photo shoot since I had to catch 4 otocinclus out of the tank to put in the pond to breed and took the tank apart to catch the speedy little things.
I have 3 fat females and a male oto who have bred in the tank before but I think the king tigers have been making a meal of the fry.
Now the otos have a heated 350L planted pond all to themselves.
Reckon I will have a seething mass of otos on the surface in a year or so? :clap:
