Well hello to all, Just to get things started I need some info on this fish before I got out and buy 1.Just give me some of the details on this fish on size,compatibility,foods,aggression,tank size needs.And stuff.....I have ryt now a 90 gallon but its too small ryt now plus they are being used by my pair of black convicts and a pike cichlid with a jack dempsey and a green terror.But in a acurrate time of the occupants....their all gone so the tank is empty.They are all in this guys 125 gallon fish tank.He bought them from me.And now a flowerhorn is in the tank alone.So i will be getting a 180 gallon tank. 6x2x2 is the dimension.And if its still abit small please tell me ahead of time because im planning on getting my uncles fishes from his tank at his house.He is goin to give me another silver arowana thats 7.5"and a managuense thats 4".He has a dovii but i dont want it cuz its goin to get big.So would a Butti be ok with the managuense and the arowana in the 180 gallon together or will their be some fights occuring once together?And its a bad idea with the arowana in a tank with cichlids then ill just keep the managuense with th Butti.And please post the full list of tankmates ok with these 2 aggressive fishes.Thanks
