I didn't realise there were so many variations, some of the ones on this post are stunning! Blastos grow like weeds in my tank, wish I could get hold of some of these.
Bought a new Blasto on the weekend has a few different colours, will post a pic later when I get one.
@ironman31 I had one head for ages on one of mine, then one day I saw the skirt was being lifted by the flow and saw about 7 baby heads growing around the base!
