Breeding Question

[Sparviter]

Hi folks. A quick question on Great cresteds/Danudes etc. If they are kept aquatic all year round and cooled for Winter, will they normally come into breeding condition naturally or do they also require a terrestrial period?
Thanks, Lee.

From what I've seen of the aquatic cristatus my friend kept, as long as they get the correct photo period and a seasonal cool stage they will come into breeding condition on their own in the autumn/winter. No terrestrial period is needed.

I have really limited experience, but I don't think a terrestrial period is needed for dobros. The dobros I got in May as subadults have always been kept aquatic, and they're breeding and laying now. The water temp in the their tank probably hasn't gotten below 58F, and it's mostly been 60-62F for most of the past 3 months.

Just a winter cooling period is usually enough for Triturus of almost any species to come into condition. My dobros have never left the water even when given the chance and will lay eggs even when they have not been cooled (usually in Fall). Species like T. marmoratus or T. macedonicus benefit greatly from a terrestrial period but not all animals will choose to leave water after breeding. There is usually an increase in number of eggs and fertility in Triturus that get a terrestrial period following breeding.
