I have kept bettas in my planted community (20g) for nearly 8 years. No problems. I have heard plakats are more aggressive, but never had that variety. I figured plakats could better fend for themselves against my passive GBR, guppies, and neons, in terms of getting to the food fast enough. Any suggestions/ oppositions? (I have had a giant 5 inch body size betta before, no aggresion, lived 4 years).
