My F2 SRD is showing a pimple thingy on his tail...can anyone help with a remedy... I have my Flowerhorn in a 48 x 15 x 18 tank(LxWxH). Pic attached below...
Does it look like a white knot? If so it might just be a broken ray. One of my large parrots has a similar looking white bump on her tail for nearly 3 years.
