I am upgrading my 40 gallons to a 75 gallon tank.
I currently have
2 mandarins
2 clownfish
4 spotted cardinal fish
1 yellow tang (small)
1 hippo tang (small)
What I want to add
2 dwarf lionfish
1 marine betta
6 firefish
6 blue green chromis
4 seahorses
1 flame angel
1 coral beauty
4 bicolor goatfish
1 walking batfish
Will a dwarf lion fish eat any of these fish? If so which ones?
Did you research any of this before posting the list? Correct me of I'm wrong but you seem fairly new to the hobby, do you realize that 7 of these fish are listed as EXPERT ONLY and are recommended only for extremely advanced aquarists and public aquariums. Also most of the fish on your list are incompatible.
The dwarf lionfish, batfish, and marine betta are all predators in nature, that will not change in your tank. They will eat the firefish, chromis, tangs if they actually are small( or are you just saying that so to not be flamed), cardinal fish, clownfish, and mandarins.
Also firefish NEVER EVER EVER do well in groups and especially in a relatively small tank like yours they will fight to the death. Same with the chromis unless in a large tank >150 gallons.
As others have told you the mandarins will starve if there are two competing for the same food.
The seahorses, batfish, and arguably marine betta require non aggresive tankmates as they are slow feeders( that means no tangs, angels, or clownfish among others) and the seahorses require cooler than reef tempuratures.
The fish that grow to large for your tank are the goatfish ( need 125 ), and blue hippo tang( needs 240 gallons) NO MATTER HOW SMALL IT IS NOW.
Also there are 36 fish on your stocking list, most 300 gallon tanks have less fish than that. That is wayyyyyyy too many fish for a 75 gallon tank. Most people would recommend under 12 fish for a tank this size.
Overall this is a very irresponsible fish stocking list. That's okay if you are new to the hobby you didn't know any better, my first stocking list was very irresponsible too untill others corrected me. It may seem like people are jumping on you but everybody here just wants to help you. You seem way to eager and if you go through with this stocking list many fish will die, so please don't.
