Bloated Male Betta

[nadajdui]

Hey everyone. Well, after several months of great health, Derlock my crowntail betta is sick! Ack!
He has been living in a 5 gallon tank with a sponge filter for about a month, but he has gone back and forth between that one and a 10 gallon.
Right now he is in the 10 gallon, which houses 3 corydoras catfish. In both tanks I've been doing water changes every 3 days or so cause they're bare bottom and I'm finicky about my fish's health after the bout I went through a few weeks ago.
Ph: 7
Ammonia:0
Nitrites:0
Nitrates: 5-10
Non planted.
AC30 filter.
50 watt heater
Symptoms: swollen belly. I think it's his belly, hard to tell with all those fins. it looks like a balloon almost. I'll post a pic up here, too so you can see.

He wasn't being as coopertive as I would like, but I think I sort of managed to show you what I mean.

Try shelled peas it might be constipation, what do you feed the fish, and what it look like when he goes to the toilet.

Look also under swim bladder.

I feed him Hikari micro wafers, as well as blood worms once a week or so.
I haven't seen him goto the toilet today, so maybe it is constipation.
He's swimming fine, acting normal. Coming to see me as per usual when I'm around. I will try the shelled peas, though.
Thanks.

Need a more varied diet as to many dried foods can lead to constipation and swim bladder.
Need frozen foods and veg in the betta diet.

Look under feeding.

Right on, thanks.

He's looking a little better today. Phew. I didn't feed him at all last night, but I will try shelled peas today and see if that makes a difference.

 

[WILDER]

Ok good luck.

Looks better. He ate some of the shelled pea I gave him. Cories enjoyed the rest.
Thanks, Wilder.
