I was looking at it more closely last night and I"m pretty sure it frogspawn. Since it been in the DT, under better lights it got a little larger. I can see multiple green bumps in each arm, which looks just like the smaller arms on my larger frogspawn. Hopefully it will continue to grow and I'll be able to tell for sure. Any idea how long it takes for the frogspawn, torch, hammer species to grow?
