pinks as food
Hi Carlos,
In addition to what has been posted re pinks:
Over the years I've seen a number of problems arise from feeding pink mice to (mainly insectivorous)amphibians and reptiles, especially fatty deposits in the cornea and liver problems. Most common in tiger salamanders, White's treefrogs, basilisk, marine toads, as I remember. These all take an occassional mammal in the wild (although studies of B. marinus in Venezuela indicate this is very rare for them) but never as a regular part of their diet. Crayfish (de-clawed to be on safe side) are a great calcium source for large amphibs. and cause no problem as a regular dietary item for American bullfrogs, marine toads, mudpuppies, amphiuma in my experience - minnows are much better than mice also.
Re UVB, too much can cause eye problems in some species - has been noted in gray treefrogs, others per a recent article - even the amount in "plant lights" was detrimental to gray treefrogs that perched in the open, close to the light - many amphibs have UVB protectants in the skin as well, so likely not designed to use it to synthesize Vit. D.
Best, Frank
