Hi I'm new to the forum my reason for joining is i noticed my baby silver arowana that ive had for about 1 month has a curved tail the fish is currently 3-4 inches in size and Ive never noticed it before he gets alittle spooked sometimes but ive never seen him slam into the glass hes in a 20gallon tank with a baby pleco (2 inches max) and baby fire eel (4-5in) water is 77 degrees and parameteres are all in line since these are my future show tank fish the 20 gallon was only temporary its my quarantine for my peacocks/haps but since it was empty i started them in there, the 55 gallon I have for them as a grow out is cycling ill attack a picture of the fish
