Just got a spottednose puffer yesterday.... have two other puffers in 90 gallon tank.. all small.... porcupine and dogface.. the spotted is much more mellow, perches in the back corner behind a rock. got it to take a few nibbles on a piece of brine shrimp using my wand and he came out for a bit a lil after... havent put the lights on yet and did a 5 gallon drip to acclimate... is this normal behavior? any food recs?
