Half Moon Betta acting wierd.
I've had my male Half Moon Betta now for about 7 months and he's been doing very well. At first he wouldn't eat but that's a thing of the past. I do weekly water changes and everything has been testing out great. I did a water change this past Saturday and since then he has been acting differently. I feed him freeze dried blood worms and normally he is very aggressive towards them. He lunges at them like there going somewhere. Well the past few nights he's been having a hard time getting them. He'll stare at them for about ten seconds then attack it but misses most of the time. I did another water change Wednesday night to see if that would help but it didn't really make a difference. He also seems very erratic with his movements. Tonight I'm going to add a few drops of Rid-Ich to see if that does anything. There's no visible parasites, fin loss, hazy eyes or anything like that. Does anyone know what could possibly be the problem? Any help is greatly appreciated.

Is he in a heated tank? If so, check the temp. Maybe the heater went. Beta do not like cold water, so if it's gotten too cold for him, he will behave more dopey.

I certainly agree. Check the temp first. It's the first thing that I check when my bettas aren't acting just right. It would also help to know what size tank your betta is in.

The other thing that I can think of is blindness. Does your betta have iridescence on his scales? Sometimes this spreads to the eyes and can cause partial blindness. I have a male halfmoon betta like this. I just have to take a little extra time feeding him. Take a look at his eyes and tell me what they look like.

Are you using a water conditioner to remove chlorine, chloramines and heavy metal from your tap water?

And when feeding freeze dried bloodworms, you should be soaking them in some tank water for about 10 mins or so before feeding so you avoid the risk of them getting stuck. It could cause cause constipation or bloating. Think of it like eating dried spaghetti.

Is he bloated at all?
