dwf, he's 2 foot, well 23 inches. DHR, I know about the size differentials. When I got the arowana he was 17 inches. The bala was 4. They've been fine together for a year. Now this. Here's a pic of the tank now.
It's an all out war in the tank right now. The oscars are going after the pleco, and the pleco is kickin their butts. Scales are flyin. The arowana is racin back and forth and I don't know what's going on, but it's a WWE thing, royal rumble. I'm about to go nuts, nothing I can do, and it's never been like this before. The Oscars are pi**ed about something.
Just had a thought, maybe their wanting to mate and killing off the rest of the tank. Maybe they did something to the bala and the arowana just ate him, because of an injury. He couldn't eat the bala because it was too quick, maybe he was injured. I didn't see the act, so it's hard to tell. I've heard of oscars doing this. They are burrowing a hole in the gravel right now. Any ideas?? Have I been thinking about this too hard and long??
