Since I added a second filter and changed to glass beads instead of gravel, the aquarium has stayed cleaner longer. I read an article, though, on why the water would turn yellow. There were things listed, such as decaying plants or fish, the use of driftwood, and other things like that, which don’t pertain to me. They did say I might be feeding the fish too much and suggested I scale back for several days and see if that had any effect.
There is a big range of how much food a PINCH is. Since the fish were all the same size when I got them, and you can see one of the goldfish is a lot larger than the other two, you can tell who is getting the majority of the food. I’m watching, trying for a much smaller pinch of fish flakes than I have been giving them. I wonder how one can tell how much is too little, good, or too much, though. The fish don’t say much…
