Hello I have a Silver Dat, a Blackstriped Pike, and two Needle Nose Gar. Theyre in different tanks right now but i plan on moving them in together. Will they get along? The Pike is with the Gar and theyre chilling. The Datnoid is currently with a Regani Pike and very rarely he chases the Regani off but usually they are chilling. The Datnoid and Blackstriped Pike fighting is the only thing im worried about because the Blackstriped is more aggressive than the Regani. All of the fish are on the younger side of their lifespan and not fully grown.
