will there be aggression issues?

[Stacyod]

I have a 30 gallon long with a ruby red dragonet. He is fat and happy. I add a bottle of copepods every other month and I grow bbs which he eats from a mandarin feeder we built for him. I am very fortunate. He also eats mysis shrimp when I feed the other fish. It’s really fun to watch. I am not worried about having enough food for two copepod eaters as I can always add a bottle every month instead of every other month. I am wondering if there will be any aggression issues if I add a mandarin to my tank. Thank you in advance for addressing my concerns.

feeding two aggressive species in the same tank may require some thought - both are aggressive species so improving the aquarium to allow each hide more may help. It is suggested they should be about the same size and gender
