Ya... we definitely need more people to post their experiences. Charles believed it was due to the knots of the worms detaching in the fishes intestines. Which from a biological stand point, makes sense. My fish were definitely back to normal within 1 hour of me removing the lev from the water column. In fact, they are eating like horses now.
I really noticed it the worms take it hard to my Bolivian rams. My female i don't think has fully recovered, but she is back to eating a lot once again and most of her color and fins have come back.
If i was to buy lev from anywhere else. It definitely would be a vet. I would stay clear of buying it from an online source besides charles
but i definitely appreciate this conversation, because i know all of these posts will help someone else one day
