So turned out Bubbles was not the healthiest of fish. One day he started to develop white spots which was diagnosed by a quick google search as Ich (Ick). We got him meds but he never did recover. Matthew was torn between being sad that Bubbles was dying and elated that he might get NEW FISH.
The day after we foundBubbles laying on the rocks we went back to the fish store for NEW FISH!
This is the pink one (they glow under the blue light).
This is the green one and in the back there you can see the orange one. I have no other pictures of the orange one because it died a few days later. As did the next two orange ones I bought. We have not tried another orange one but... the green one, the pink one and Rocks seem to be doing very well.
Unfortunately, this has all left a terrible scar on Alex. When we read color books and we get to orange he says "Orange Fish...Dead" over and over again. Sigh
