I don't have much experience on gars but I have has my spotted gar about 2 weeks now and he is great! They just look cool especially when stalking food ( already dead fish but he still has to kill it lol ) and no way do all gars fit in a 220g before this I brought an alligator gar (spatular gar) and returned it when I learnt they naturally grow to 3 meters! Makes the rtc and stuff like that look like minnows... But my spotted gar is cool, only thing I have actually seen it eat is defrosted silversides but he takes them readily, I cut some of them up for the smaller fish but he ate a whole 1 that was for my catfish and I was about half his size lol
