Buy a shark. Just kidding
Maybe try to place a real big net in the tank and hold it there, then drop some pellets in the tank? Other than that, I have no idea. I'd start moving rock.
Cut the end of a 2 liter soda bottle. Put some rocks in it to hold it down on the bottom. Make sure the back of the bottle is higher. Put a chunk of frozen food in it and wait. When the fish you want swims to the back to get the food cover the hole with a net and you got the bad boy. I have caught a lot of fish this way. Works every time, You can also shave the barb off a ice fishing jig and use shrimp.
The EASIEST method.Betts Fire Fly Shimmy Flies
And it wont hurt the fish,as long you either get barbless flies,or file the barbs off first.
Just remember that once the chromis are hooked,to gently net them and remove the hook with a set of hema-stats BEFORE bringing the fish out of the tank.
