Hi everyone ! Im fairly new to this saltwater aquarium world ! We have a 36 gallon tank that we have had for a while it was doing really well for a while and then it seems keep losing fish, we did have a one with fin rot and we eventually lost it, I tried to treat it but think it was to late, we now have a just a snowflake eel and a Fiji orange tail Puffer in there , I have them separated as we are going to be moving into a 54 gallon tank and letting the snowflake has his own space. The snowflake seems to be doing great an the puffer seems to struggling a little bit and seems lethargic, maybe I’m just nervous since we have lost some fish
