A mere two days after we got them, one of our little fishies past away. I thought it was the crazy one which was speeding up and down the tank. I woke up the other morning and spotted one little golden fish floating at the top of the tank, with one of it's eyes pointing upwards. It was very sad. But, it would appear that the crazy one is still with us, and is still swimming manically around his tank. The other weekend we heard some odd splashing sounds from his little tank, which turned out to be him jumping up on top of the seaweed.
He spends most of his time being very energetic and doing acrobatic fishy tricks, and very little time going anywhere near the vase-shaped tunnel ornament that I bought for him.
