1 6" silver arowana, 2 Sveni ciclids 3" and 4", 2 whiptail plecos, 1 albino bristlenose pleco, 1 farowella, 1 whiptail farowella, 2 other unknown species catfish, 3 bamboo shrimp and 5 fiddler crabs. The 75 gallon tank they are in consistantly is stocked with 1-3 dozen guppies, 2-3 dozen ghost shrimp and 1-2 times a day I feed them live blood worms. I will be getting a 125 in 2 months then a 200+ gallon next fall. Will a snakehead be okay with these roommates?
