    Betta Fish Diseases and Emergencies
    When I bought my little betta (whom I have named Dragon) he had a light gray marking on his head that would shine almost white when the LEDs in the hood of my tank shined on it. Today is the 6th day that I've had him and I noticed that now the spot has become this cresent shape. I think maybe...

    Betta Fish Diseases and Emergencies
    Hi. I just looked at my betta, and just noticed a bright red raised spot on my betta head above his eye. The scales all around the spot are faded and 'dead' looking.

  9. Favorite Hiding Spot?

    Betta Chat
    I realized my betta is crazy about this pink rubber plant he's had ever since I bought him. He burrows his body in there and becomes completely invisible. Some times he only sticks his little head out like a little eel.. haha. Does your betta have a favorite hiding spot?
  10. Troubling pink, fleshy areas on scales. Some coloration on fin too...

    Betta Fish Diseases and Emergencies
    Found Cobalt this morning with strange pink spots on his scales. It's like his blue scales have turned a pink, fleshy color (picture attached). It's been over a year since I've had him and this has never happened. I'm thinking it may be related to the mini-cycle I am finishing up since I changed...

    Betta Fish Diseases and Emergencies
    Hello All, I originally posted here on 8/9/12, when I noticed my fish had a "blotch" on him. Well, it stayed the same for a while, so I thought is was just coloring, as another member had suggested. As of a few days ago, there has been a change. Now it has turned into a white spot. I'm...

  14. Cobalt has a white spot on his head, pacing

    Betta Fish Diseases and Emergencies
    Cobalt has been acting strangely the past few days. He continually paces in front of the acrylic, and flares occasionally. I figured this was fairly normal since he has to get used to seeing his reflection, etc. So this morning I went to his tank and found he has developed an odd white spot on...
