I have a mainland-type unsexed that weighs 280 grams. I purchased it about 8 months ago prior to color change and at a weight of 90 grams.

I believe it is a male based on the fact that it went off feed for about 2 months, but I plan to have it probed at some point.

My understanding is that males reach sexual maturity before females. If this is the case, without not knowing its actual age is there an estimated weight at which breeding attempts would be recommended?
