Betta with clear spots on fins

19 years ago

My daughter has a dark blue (almost black) Betta as a pet at her college dorm. For the past couple of months, we have "inherited" the Betta at our home since her dorm is too cold for it.

The Betta seems very healthy, eats well, flares at his reflection, and swims around normally. The tank is a 1 gallon tank (limited dorm space) with a 7 watt light to heat it. Water is changed frequently and kept at 75 - 78 degrees.

One thing I have noticed is that his lower fin is beginning to get "see through" spots in a couple of places. These are not near the edges of the fin, but are less than half way out from his body. Is he just changing as he ages? His small swimming fins have always been almost clear since she got him.

I have read books and searched websites, but none of the diseases listed there sound like this. Is this an illness or just a change in his coloration?

Do you have a picture of it? I know... that would be hard to capture and probably wouldn't be clear. It could be the beginings of a bacterial infection. I would try a bacterial medication as a precautionary approach... something like a furazone / furan green and see what happens.

Thanks. I'll try that. It would be almost impossible to see in a photo. I understand that Bettas will fade as they age, too. This Betta is about 1 year old (plus however old he was before purchased) so I wonder if it might just be age. Is there any harm in using the furazone/furan green if there isn't a bacterial problem?

Where do I find furazone / furan green? Would it be OK to use a milder treatment like Betta fix/Mela fix?

I've lost track of the newest hardline items, so I'm not familiar with Melaafix. What does it say it will do? Furan, Furazone is safe. A lot of these dyes that are bacterial fighters are used as preventative medication for shipping. Your local pet shop, one that specializes in tropical fish, should have it and similar medication.
