Q:
Hi - I cleaned my betta's water today, and since then, he has been
acting odd. He stays at the top, or when he tries to swim
down, he bounces right back up, like he can't stay 'down.' He
reacts to seeing my other bettas, still (flares out), and ate his
food, though. Any ideas on what might be wrong with him?

As a matter of fact, I do :). Your betta has swimbladder disorder.
"swimWHAT?" you ask? OK, here is our "Swimbladder
101" crash course.
The swimbladder is a handy little
device that stretches inside your betta's body alongside his spine.
The function of the swimbladder is to allow the fish to control
where he wants to be as far as depth is and to maintain its
position. Fishes that do not have a swimbladder cannot
"hover" in place but instead are condemned to swim night
and day (many of the fish that live in schools in the ocean do not
have swimbladder).
Our bettas however are the
"Deluxe" model and come standard fully equipped with a
swimbladder ;) and since they do not have to swim to maintain buoyancy,
they have the luxury to be as lazy as they darn please (which,
usually is quite a lot LOL).
But sometimes the swimbladder goes
bad. Too much food, or stress or sometimes certain diseases cause
the swimbladder to malfunction. Sorta like electric windows on cars
LOL they're great to have, until they stop working properly that is
;). Since bettas are 'made in Taiwan' ;), expect the bells and whistles
to go bad on this model rather promptly LOL. What you are left with
is a betta that cannot swim properly. The main two way things can go
at this point are:
Betta cannot swim 'down' and
maintain its buoyancy and floats pathetically at the surface,
usually on one of its side. If that is the case you can usually
SEE the swimbladder protrude as thought it is swollen or full or
air (like a long balloon). You are likely to find it protruding
from the side which is floating UP. Betta may try to swim down
but it is like it is spinning its wheel for nothing and floats right
back up. In a way, think of it as though you had little
floatation devices around your arms (like kids do) and you were
trying to swim under water. Pretty darn hard, huh? For Mr. Betta
it gets very tiring so he will prefer to just 'lay there' at the
surface. Although this lying around cannot kill him (as all lazy
people and couch potatoes will attest LOL) it makes feeding very
difficult because lining up the mouth with the food becomes an
all time out effort (oftentimes a useless one). It might become
necessary to hold the food with tweezers and aim it directly for
his mouth cavity. In your case, you mention the betta is still
flaring which to me indicates the ability to swim (at least
temporarily) so that is a good sign.
Betta cannot swim 'up' and
lies pathetically at the bottom of his jar. Going up to get a
gulp of air or food is a huge effort and the betta immediately
sinks right back to the bottom. In this case you will not see
the swimbladder protruding. It is more likely to actually be
contracted if anything (like a deflated balloon ;) ).
Either way you look at it, whether
down or up, stuck at the surface or stuck at the bottom, your betta
looks pitiful. But do not give up hope. Just as the
swimbladder malfunction seams to appear overnight, it oftentimes
goes away on its own. Meanwhile, lowering the water level might be
kind so Mr.Betta has less efforts to make when trying to move up or
down. Or you could install a betta elevator, but they often get
stuck between floors, so it is a bit risky (just kidding ).
If he cannot get to his food use the tweezers trick mentioned above.
Keep water clean and use a broad spectrum antibiotic to help fight
any diseases that might be causing the problem. Feed a lot less so
that Mr.Betta's belly does not look "full". Favor two very
tiny feedings a day as opposed to one large one. Overfeeding is the
#1 cause of swimbladder disorders. So feeding less may rectify the
problem. I woud start by not feeding the betta for 3 days, and then
feed twice a day in TINY amounts.
Most of all DO NOT GIVE UP. He
will probably bounce back, but it may take up to 6 weeks (or more),
so be patient. I hope you do know how to perform water changes
properly and how to treat the water so it is adequate for bettas.
