Concern on new Betta's tail

[Laki]

Oh, where do you live? I buy mine off ebay lol It could be a local residue from pesticides or pollution.

More likely, I think the surface is covered from excess protein from the pellets. This is a common thing to happen and it confuses a lot of people at first. Sop it up with a paper towel, the oil should just stick to it.

I live in Malaysia. Haha, at first I didnt know what "Indian Almond Leaves" was until I was told it is "daun ketapang" in bahasa. Thn I went searching for it like crazy. Thank goodness it is easy to track one when there are red leaves on the trees. Else, it'll be like any other. =.=''

But the thing is Zeus eats it immediately. The protein builds up the moment the pellets hits the water surface? The substance also occur on other tanks which I dun feed this "Sanyu Betta Gold" pellets.

OH so you're lucky to get the trees there!! Awesome!
(*what's it like there, I always wanted to visit!*)

As soon as the pellets hit the water some of the proteins residue sticks to the water-kind of like the opposite of adding dish detergent to a pan of oily water and it immediately disappears. This is totally harmless but it does happen.

Since you're using this as his hospital "tank" it should be cleaned every 2 days. Once you get a larger tank for your fish you might notice less of this on the surface of the water at feeding time.

But when you do upgrade, you will find your fish so much happier and active! This will encourage his tail to get better.
