Long overdue update! Went away for a few weeks (fish were looked after) and the polys are doing well.
No more worms, the treatment went perfectly and no resurgence. Thanks again

Both are eating, growing and pooping a good amount. Mainly pellets but toothless ate a long ass worm

Managed to catch her yesterday and pushing over 6" now which is awesome. Nibblet still seems smaller and hides away during water changes, or often clings around the plants
WC toothless is AMAZING. Really eating now, fins look great and she is always cruising or swimming about. Lovely fish for sure
