Hi do you a local store that sells salt water fish coral and invertebrates that may be your best option for finding a healthy fish I purchased a little gobie from a local Petco and have had it for at least a year and a half and it loves the surroundings it resides in it nips at my hand.
Looks like they are doing well roll the dice and see if you win or lose we really do not know that much about what happens in the ocean or what really happens in your tank if conditions are right you may reach a well balanced system that will grow and become a small piece of the real ocean.
Here’s is pic from the front of my tank of a red monti and a green monti facing the back of my tank. The red one is an in tank frag relocated to its current position.
Hi I have a very simple system.I have 2 fluval 10 -30 gallon aqua clear filters and a small powerhead the only media in my filter is ceramic tubes I use a small led light made by current it has a basic sunrise and sunset mode that seems to work well in my system I use nature’s ocean natural sea...
Did you try to feed it add some p e mysis shrimp that may help. Corals need to eat and in a system that has few micro organisms they may starve to death.
