I've heard stories of the cleaning shrimp's routine. Look forward to seeing it in my next tank. I'm happy with the puffer and will keep it for a couple of years until we move.
Yea, I've been playing a little.

Just changed the lighting and lighting schedule after adding a DSB. I'll calm down for a couple of weeks and see what happens.
The tang nibbles on the puffer occasionally, mistaking it for a piece of LR. The puffer shakes a little and slowly rises off the bottom like a blimp and looks around to see what happened. I imagine the puffer will bite the tang one day and that will be that, one way or anotherââ"šÂ¬Ã‚¦or the tang will discover the puffer is not LR. Either way it's out of my control (unless they start fighting-then I'll intervene).
Overall the behavior of the fish is lively with no scratching. Their appetite is great. They donââ"šÂ¬Ã¢"žÂ¢t chase each other.
The tang rules the tank and has a voracious appetite. It gets greens daily (soaked in garlic and vitamins 3-4 times a week). It seems extremely happy and very colorful. No reason inside the tank for it to be stressed (only meââ"šÂ¬Ã‚¦.on the outside). Darn it.
Your comments about a possible infection do make me a little nervous. Of course I must have already been a little concerned or else I wouldnââ"šÂ¬Ã¢"žÂ¢t have started looking for a cleaner fish in the first place.
Do most fish accept the neon cleaner gobies in the same manor as a true cleaner goby? I have a small bird wrasse in there now (1 1/2") and no one seems to care. It swims in and out of the LR. These tank raised gobies are about 3/4" when they come in.
