Wassup everyone....man it's been a long time....I want to get a Managuense....Is 1 ideal for a 75 or could I squeeze in 2.....i have my 220 that I could always put 1 in. Honestly I would love to buy more than 2 and see if I can get a breeding pair. I wouldn't mind buying a bigger tank...but not too big as this tank is going in my room.
