frogspawn question

[GreenSpottedPuffer]

I have two different kinds of frogspawn. The more common one and this one which I don't see as often. This was a month or so ago when I first got it and actually believe it or not, it has colored up even more now. Its also started to really 'extend' its flesh way down the skeleton the past few weeks. One of my favs in my tank. Its never as 'bushy' as my other frogspawn but since its happier now than when I took this pic, it ids a little more 'open' and full.
