So i got a female motoro ray. Its currently in a 40 gallon tank. Before you guys start getting upset, its only temporary. 2 weeks max for quarantine and deworming/parasite and whatnot. She is about 5 inches in diameter... and the lfs had her on black worms. Not that i have a problem with black worms, when can i start pellet training it? should i go by the disc size? or should i measure by the tail's thickness? I'd like to get it off live and frozen asap without disrupting its growth. This is my first ray, please bare with me. and after 2 weeks of making sure its all good it'll go into its brand now 300 gallon tank with a male (which will go through the same procedure). any kind of tips would be great! And yes i have read the stickies, they only tell you what to feed, not when.
