I have two fire fish, one is swimming in the current and acting as i would think "normal", (my first salt water tank) the second seems to intermittently lay on the sub straight, not on his side straight up and down looks to be resting. It is a bit smaller than the other, a bit skinnier, it was eating ok and does go after food when put in the tank, although i have not seen him grab a pellet in the last day just swims up to it. fins look good color looks good tank perimeters are ok, im only measuring nitrate (5)and salinity(1.26) and temp (about 77). at this point no coral yet and i do not dose anything. 10% weekly water changes so about 5 gallons for my 40 breeder with 10 gallons in the sump. maybe the temp is too low or i should change food, i feed pellets in the morning and brine shrimp in the evening. i get more attention when i feed the shrimp. or could this be normal behavior for this fish?
