I just adopted 6 bullfrog tadpoles today. 4 of them have back legs and front legs, with a good amount of tail still left. The other 2 have nicely developed back legs but no front legs as yet.. I offered them some Romaine lettuce, as well as baby spinach, but they had no interest. Should I be feeding them something different at this stage of development? I have some freeze dried blood worms and also algae thins, would they eat that? No one has left the water yet.

Other Info: All the tads look healthy. I have them in a 20 gallon long tank. Temp is 77 degrees. Water is free of chlorine and other contaminants. Tank has water and land area.

Any help would be greatly appreciated.

Thank you.
