ummm they are right dude im not tryin to lie or say nething i mean it is ur tank but ok i had 2 rbp 1 8" 1 5" and a spilo in a tank together, got them all for free cuz a bunch of ppl were movin around and didnt wanna give em to a lfs so they tolerated eachother for about 8 months then 1 day i came home and the spilo was bit in half. the big one then preceeded with eatin the 5" too, they werent grown up together ether idk just a lil advice. also i no longer keep p's but i used to and all my cousins did too thats why i got all those for free. i love spilo's one of the most beautiful p's out their in my eyes
