About the Garfish...
Someone must have just put them in that "small" tank, or the water or temp was not right for them. They are showing good signs when at the top of the tank - not hugging the bottom. But, the coloration is still there.. ..just a comment, no reply expected..
they are at the bottom like half the day, the rest they kinda mozy around, its a 60 gallon.. shared with a few oscars and the like. when we got them they were almost white, they eat goldfish like potato chips hehe
