After genetic study, what used to be called Ranitomeya lamasi and biolat are now grouped into sirensis with the distinctively different holotype, a solid red frog with blue legs. I've observed the most activity around lights on and lights off, these frogs are typically shy. They make up for their shyness with a lovely call, much like that of R. imitator, the ability to be kept in groups and a willingness to breed.
Breeding takes place just about anywhere and 1 - 5 white to gray eggs are laid at a time. The male readily transports the tadpoles to individual bodies of water and directs the female to lay nutritive eggs for the tadpole. If tadpoles are pulled they need to be housed singly and fed a high protein diet.
Care: Beginner, the high price and limited availability of the Highland/Tingo Maria morph should prevent them from being a starter thumbnail, typically shy
Groups: Yes, even mix
Breeding: Easy, horizontal film canisters on their sides, upside down vertically from 90 to 30 degrees
Tadpoles: Excellent parental care after deposition, recommend leaving tadpoles with parents
Froglets: Small - Medium, springtails are a help, tadpoles left with parents morph larger
Tips: Lower light levels result in bolder frogs
