Has anyone ever had a problematic chromis? I have had a chromis in my tank from the start for cycling. All of my invertebrates are doing fine but I am still trying to figure out why my first clownfish jumped out of my tank (with a lid on) and why my other one died in a matter of 45 minutes after it had been in the tank for 4-5 days and eating. Any one have any knowledge on this?
I would hope you didn't cycle the tank with the fish in there? If you did, its possible that they have finally succumbed to ammonia toxicity.
I'm also going to assume your not QTing your fish? If your not it could be any number of things. From flukes to ich to brook. There is a reason we advocate QTing anything wet before it goes into the display.
Chromis are very aggressive, despite seeming like a friendly community fish. It's actually misinterpreted because it is small, and because they school together in home tanks. The reality is that schooling isn't a natural behavior, in the wild they sit in a coral head all day long. When in an aquarium that they don't have cover in, they stay together in a tight group in the water column, and because they're so agitated, they are often much more aggressive than when they can relax, and will chase other tankmates out of the tank, particularly at night to fish similar in size to them.
That's why so often people with a school of chromis end up losing them one by one, usually by jumpers. It happened to me, and I was always curious why these peaceful fishes were jumping out of the tank.
Some clowns are also very excited and swim through tank frantically at fast speeds and up and down the corners. Could be this was the case for the carpet surfer. The last one is mystery, water temperatures during the day or night could also affect them. Get a few more chromis and let them school before you start spending money on a nice clown. Sucks man that's money thrown away I would just hold off on any $$$ fish purchases and see if anything else in tank doesn't make it.

After reading a bunch of comments, I finally got rid of my chromis. I am convinced that the chromis was the devil. So I took back the chromis and the leather coral to the LFS and bought pair of ocellaris clownfish. This is my last shot with clownfish haha. I also got my water tested and everything check out on spot. I bought them as juveniles and I hope they pair together. I also bought a little frag of a mushroom coral. I wedged it in the rocks pretty tightly, I waited 30 minutes and turned back on the pumps. I came back in an hour later and the frag was gone. so hopefully it pops up somewhere.
They look great! These ones will make it, I have a feeling about them... :fish1:
Tanks looking great man! Hope the new clowns do well
same here! you have two clowns right?
I have a good feeling as well! It took 30 minutes to catch that dang chromis. hopefully with him gone there is a new atmosphere in my tank. A pro-clown atmosphere
