Maybe their not getting enough oxygen, buy one of them things that make air bubble go through whatever you have them in. Are you feeding them enough. That's all I can think of now, ask a specific question and I might eb able to help.

Also what species are the tadpoels of.

honestly i still havent figured out what type of tadpoles these are....
i know one of the worst factors in my tadpoles is probably their water.... i am so stumped as to how to care for them dealing w/ water changes
i have had frog eggs that i try to change their water and they die
i leave them in their natural pond water and they die
i change tadpoles into fresh water which has been sitting for a few days to become dechlorinated, but they die
and ive left tadpoles in their natural water and they die

this water is soo much trouble! i will take the advice for the air pump, but what else can i do?? i feed them just enough, they have light and shade and a good room temperature... im just so lost and i dont want anymore to die! please help!

ALSO VERY IMPORTANT my upland chorus tad is the only one left of his bunch and he has all four legs now.... what should i do for him... anything special? i really want to keep him alive! how long do you think until he will be a froglet if he just developed the front arms today?
