I have a 55 saltwater with live rock and mandrain gobies in it for now. I have a 10 gallon salt with my seahorses and a 10 for my oscar and parrot fish.
welcome to the forum!!! how long have you had the oscar and parrot fish? those two fish together, are going to need at least a 75 gallon tank. keeping them in a 10 gallon for too long can be very harmful to them
