My Betta's poops are usually orange/brown. They eat pellets Mon - Fri. Saturday is treat day so they get peas in the morning. In the afternoon I let them see each other through their tank glass and they play & flare up a storm at one another. They usually both poop during the session from the peas. In the evening they get bloodworms. Sunday is a fasting day. Keeps 'em regular. This past Saturday, Rainbow, my 3" red/blue/teal Halfmoon guy had been a little stopped up. His poop was pea green wrapped around the usual orange. Sometimes their poop floats. Makes it easier to scoop out. Yes, I check every day and scoop it out when I see it.
