Grant :). Not being able to see your betta makes it difficult for me
to tell you for sure what is going on, but here are a few things to
know or look into:
|What kind of partition does
your small tank have? Does it allow water to flow through? If so
it should have small openings, such as holes or even slits. If
the openings are too large, male bettas long fins may go through
them as the betta rests against the partition. Another male on
the other side may promptly proceed to chew on them (chomp
|However you mention
"female", so I guess you have a female on the other
side. Usually females do not go after fins in a partitioned
environment. When in a spawning tank however, all bets are off
So that leaves me with two
possible scenarios here:
|If you have plastic plants,
they may be the culprit. Some plants have sharp leaves and
betta's fins will overtime get caught on them and start tearing.
Select plastic plants with ROUND leaves that have no pointy ends
or sharp edges.
|If your male has long fins or
is a halfmoon (with heavy finnage) it may have "blown"
its fins. This is a common problem where the male's fins end up
tearing because of over activity. I would assume that the
presence of a sexy gal on the other side would cause such
hyperactivity on his part LOL.
|If this is a pet store betta,
God knows heavy finnage is not going to be the problem here LOL.
All of them are pretty much veil tails which are very narrow,
and unless a veil tail has very long finnage, I don't see how it
could "blow" a tail LOL. So your betta may have fin
My two cents: I would remove the
female and place her in another tank/jar. This will have two
benefits: The male should calm down, hence less chances of further
tearing his fins and if it is a fin rot scenario, the female will
not get infected (hopefully she has not yet). Next please check my disease
page and see if the description of fin rot could apply to your
betta. Since you are a novice, I would play it safe and treat him
for it anyways. It is often hard for a beginner to tell blown fins
from fin rot. Bettafix will not, in my opinion, be a suitable or
effective treatment. Instead use the medications I listed in the fin
rot section of disease page. To be safe, put female in some bettamax
for a week or two. Prophylaxis. In time, when your male has fully
recovered, you can put them back together, but this time keep an eye
on them and if Mr. Betta is too overactive you might want to find
two separate tanks for them permanently. Hope this helped you.
