The white mushrooms are the ones that i was talking about before that got bleached from stress when i first put them in...they are getting better,SLOWLY!! you can see i have a stinkin' problem with those freakin' flatworms and it drives me to drink...the first pic is a double mushroom??? i just picked up from a guy in Austin...it is the size of a softball when it is open and the one has 2 mouths...i don't know what the heck is going to happen, but it was only $10, so i took it and hope for the best!!!
