Hi, come June I will be upgrading from a 30 gallon tank to a 120 gallon tank and came up with a list of PREDATOR fish and also tangs that I would like in the new tank. Here is what I already own: 1. Miniatus Grouper (Baby) 2. Snowflake Eel (8" long approx) 3. Panther Grouper (newborn, size of my thumb; currently in quarantine to avoid getting eaten) Here is what I want: 1. Bamboo shark 2. Black Volitan Lionfish 3. Radiata Lionfish 4. Blue Spotted Puffer 5. Blue Tang 6. Yellow Tang Note that since the grouper and eel I have now are small in size, when they get moved to the 120 gal. I want them to be with small/medium tankmates (tangs a little bigger, to avoid tank bullying) So what do you think? Any no's but's if's etc?
