Here is the setup for the great green chromis disappearance, I have a just getting settled in 150 gallon tank that has been up and running for about 4 months now. Running 2 150 W MH for 7 hours, with 96 w accents for a couple hours before and after the halides. With a 29 gallon sump/fuge, octopus NWP 200 skimmer, sand/rock/pods/chateo, and a mag 9.5 return pump. For added flow a koralia 1 and 3 along with a penguin 660. The take was setup using water and live rock/sand from a very well established tank. So it cycled somewhat quickly (about a month) there has been a six line wrasse and a hermit crab in the tank since day one, as they came with the rock. Being so new in the hobby I didn’t realize how territeral a six line can be.
After the water parameters came in to line with a cycled tank I added a small cleanup crew. (About 15 snails, a cleaner shrimp, three peppermints, ex..) A week later a foxface was added, another week added two banggai cardinals. Shortly after a lawnmower blenny, which the six line harassed to death. A few weeks later I jumped in over my newbie head and added a copperband butterfly to combat the apitsia.(which he is doing a great at) Then a black and white false percula with a regular false perc. Then a midas blenny. The live rock that I put in the tank also had a couple strong red mushroom colonies that are doing great and spreading along with some green button polyps. So the tank is doing great so far and my only loss is the lawnmower blenny that I’m blaming on the six line.
So for some color and because I like the effect I decide to add four green chromis, all I could find where what I would call very small sized ones(3/4”). Added them to the tank and all is well for the first four days, fish are swimming in the open water, all four are eating great. The morning of day five one is missing, I think must be hanging out in the rock work. Day seven no sign of the missing fish, but the other three are doing great, later that night there is only two. Day eight there is only one out and about and the cleaner shrimp is seen finishing up the remains of a green chromi. By the morning of day ten all four are gone. To my knowledge I’ve listed everything in the tank except the bristtleworms, I don’t know of anything else in there. What could have took out all four green chromis, what seems to be one by one? Everything else in the tank is doing great.
Temp 77 – 79
PH = 8.2
Salinty – 1.025
Alkalinity – 10 dKH
Nitrite – 0
Ammonia – 0
Nitrate – 5 – 10
That’s all I have test kits for, for the moment.
I know this is way long, but I know how you guys love all the info you can get, any help would be great, thanks.
