Mine seem fine, thanks for asking, Colin.
I have so aqua scaped their tank that I cannot even count them anymore on a daily basis.
I can see eyes and fins moving and I know there are five still but I do not really see them unless it's sand tilling, vac'ng all sand time or it's feeding time. Even at feeding time they are pretty much swoop and run. But I love them.
My two oldest are probably 5 inches my next two are prob 4 inches and my youngest is prob 3-4 maybe. The youngest is the slenderest and a slightly diff colour. I am thinking I have 4 girls and one boy but I am not sure. The only time they swim the tank is when I am not in the room or at work so it's hard to capture their bellies against the glass for a picture. If I sneak in at night after work and use a flashlight I can see them swimming all over all water levels but soon they discover i am there and take cover. they peek at me from behind things and wiggle their whiskers.
I will try to get pics of all 5 so you can see tho. And they really like the bigger black ABS pipes best. Altho they do go into the white pvc and they are all over the driftwood.
I havent had one by the heater or intake tubes in quite awhile.
