    Hi Guys,

    Hopefully someone can enlighten me on what is happening to my new Betta. The photos will say it all:

    Thursday afternoon

    Saturday evening

    The colourisation of the fish looks slightly different in the photos, but that’s because of the lighting, it is actually still the same colour as the first photo, but with the black discolour.

    Can anyone help me uncover what this is and how it can be treated?

    Thanks in advance!
    Neil

    Hi Neil the position of the flash on the second photo confuses things a bit but I’d say that’s caused either by stress (in which case it should be temporary if the fish is properly cared for) or excessive melanin production (nowt you can do). Is that a shadow or dark colouration on the lower half of the body in the first pic?

    I believe it to be dark colouring Matt, but the little guy won’t stop dating about the tank to see clearly.

    My tank peramatures are:

    biUbe 35L
    New cycled and fish stocked on Wed/Thu
    Ammonia – 0.25
    pH – 7.5
    NitrIte – 0.25
    NitrAte – between 20 & 40 on the colour chart (more toward 20 I’d say).

    He is also eating like a PIG!

    Could it be caused by him rubbing his side constantly, as he likes going behind my Riccia wall background which has a narrow gap, he enters this possibly rubbing the blackened side each time? Stress in this case could be a good shout as he is swimming in a circular motion around the perimature of my biUbe tank only stopping at night or to feed.

    Cheers for the help Matt!

    hmm, could be a combo of both the damage when he gets behind the riccia wall and stress.
    bettas dislike fast moving water preferring it almost stagnant. also, are there any other fish in the tank.
    you could try a half dose of melafix for a few days and try blocking off the riccia wall to rule out that as a problem.

    I note that there are both ammonia and nitrIte readings at present. These can be a cause of stress due to the discomfort that the fish is in caused by gill irritation, and that would explain the rubbing.

    I’d recommend daily 50% water changes to keep the ammonia and nitrIte readings as low as possible, and whilst it is a good sign that the fish is eating well, I’d also cut back the feeding to a small amount every couple of days. The less that goes in, the less waste that is produced and this will help control the ammonia and nitrIte levels. The fish will be fine – much of what it is eating at present will be going straight through and not being used for nutrition.

    Can’t remember if you’ve got another tank, but if you have then swap part of its filter media with that in the 35L, or squeeze its media into the 35L. If you don’t, see if a friend or your LFS will help. Either method will give the bacteria colonies a boost.

    Cheers for the help Eyrie, but he isn’t actually rubbing himself on purpose, it just happens when he squeezes through the gap on my Riccia wall.

    As for the feeding, I have 7x Cardinal Tetra and 2x Panda Cory (which are fine) to feed also and the Betta is eating their food before is own floating Atison’s Betta food.

    Thanks Kieth, I’ve decided to remove the Riccia wall and I’ve reserved Melafix in my local store to pickup at 12:30, so I’ll do a 1/3 water change and see how that goes.

    Cheers guys! /wink.gif” style=”vertical-align:middle” emoid=”;)” border=”0″ alt=”wink.gif” />

    I’ve just read that Melafix is bad for Betta (labyrinth fish), so have any of you used it?

    I’ve only heard that once, but I know a number of people (including myself) who have used Melafix with anabantoids and noticed no ill effects so I’d write it off as an internet myth. I’m open to persuasion if a good reason can be given though, so do you have a link to that claim?

    PS: I’d still deal with the ammonia and nitrIte readings in the tank, and the other fish will be fine with being fed on alternate days.

    I notice this thread has not been updated for some time. I wonder what happened in the end. Did clearing the ammonia and nitrite help?

    Hi Steve,

    I removed my Betta and put him in a 10L cube of his own and he’s flourished, so yes removing the ammonia and nitrite did the trick.

    Cheers for the interest.
