If you are pointing out the "white bugs" on the glass, they are copepods. Totally harmless, a great sign you have them. They can be food for some fish and part of the clean up crew for your tank.

So i understand this, you lost a clown and a butterfly fish because they both jumped out of the tank? If so i would recommend having a lid, i never run a system with fish without a lid for those reasons.

Do any of your fish have "white spots" on them, as if salt was sprinkled on them?

Hi, yes I have lids on it.. But it jump off as well. No white spot.. Last 2weeks I went out for holiday.. Lost 7fish which box fish and damsel disappear n pipefish lost in sight..

How big are the fish?

Your tank seems small for both the amount of fish and species mix. That could be a contributing factor...

How long has your tank been setup? They may have been fighting and jumped away, but thats only a guess. If your lid is off and they jumped, that sucks but happens. Did the white spots look like something that attached or was it crawling? From the pics, i only see copepods which are good.

No offense but your tank (40G) is way to small for all of those fish and bio-load. I would not be surprised if you have an ammonia problem and or an aggression problem. Those Tangs should be in much larger tanks let alone in a 40G with other fish.

Great point i missed the size of your tank. Agree with above. You may also want to invest in a better lid that fits snug or has weight to it.
