hi Leigh-Anne, sorry to hear of your losses, can you tell us more about your set up, how old, what kit you have, what tests you do, water change routine, do you use R/O-salt mix etc, the more info you give us, the more help we can be.
2 fish is about the limit for a 38L tank I'm afraid... Marine fish generally require a lot more water per cm of fish than freshwater fish. (This is part of the reason they cost more, because shipping cost is relatively higher as you have to ship in more water)
Hi Leigh-Anne! Welcome to MASA! Sorry to hear about the fish that died.
Everyone asked already - BUT, what I would like to know, is:
- how new is the tank? (or old)?
- when did you get the fish?
- it is possible, that IF you added the fish +- a week ago, that the fish was caught using cyanide
- what else changed in the tank -> temp? nitrate levels? pH? ammonia? was there a power outage?
