my boyfriend found some salamander larvae in a stream... he has about 7 total... a biologist suggested that the salamanders are many lined salis. the baby salis are in a tank w/ their natural water. he feeds them newt pellets and fish food... theres some bark and rocks for when they mature to get out of the larvae stage... however hes noticed a couple have been dying on him... is there anything hes missing? should he be doing something else for the little guys? what kind of care should he give to them if what hes doing isnt right?
