Last week I set up a 3 gallon tank for my King Betta; Jack. Since I heard so many good things about live plants, I decided to go natural. For the most part, it worked well. I also put in a tank heater and I thought Jack would be in bliss.
However, my husband and I came back from a weekend trip (adult step son was watching the house for us) and Jack was huddled up on top of the heater on the edge of the bowl after he'd been very active and interactive prior to the weekend away.
As we were settling back in, my husband noticed that there was a white "mist" surrounding the terra cotta skull (it was purchased from Petco) and the moss was sluffing off debris. I tested the water and everything came back normal. I did a full water change just in case. Jack perked up for about an hour but then returned to his heater again.
This morning, I came in to feed him and again there was the white mist surrounding the skull and debris was floating all over the water. That was it; I'm not going to sacrifice my Jack for the sake of "looks cool"...I threw out the skull and did another water change.
Now...Jack is just fine! He's even playing with his reflection in his mirror again!
Has anyone else had this problem?!? The people at Petco said that the moss was safe but I'm not so sure.
