I'd love to have a 150g! That would be awesome. It looks like you have a nice collection of large tanks there. I hope to eventually upgrade my Malawis to atleast a 125g for more room.he's in the 40gal for now with a kribensis, im moving the krib to my 55 in a few days, and then i plan on adding 4 more fronts, keeping them in the 40 until they outgrow it, then moving them to a 150 long
