djvant Posted February 4, 2011 Report Share Posted February 4, 2011 Ive got 5 silver dollars, 3 ive had about 4 years and the other 2 i purchased just under a year ago. They breed every few weeks, three males and 2 females. One of the younger Dollars is a male that has just started showing his colors when they breed. Since starting to show his colors i think the other males have started picking on him, as has only happened since he started coloring up, not sure as haven't seen them picking on him myself. Has had his fins ravaged, missing top of tail fin, one of front pectoral fin, and anal fin ripped off. He just hangs around the heater in the corner of the tank, except for feeding time and is continually getting heater burns, getting very scarred. All of the other silver dollars are in excellent condition. Are the other males likely to be picking on his now as he matures, if so is there anything i can do to stop it? Will stopping there breeding cycle stop them picking on him, and if so is there any way of stopping there breeding cycle? Or could it be something else? Tank is 350L, other fish include bristle nose, tiger loach, zebra loach, skunk loach, rainbow shark, kribisis, angel fish, lemon tetras and flying foxes Quote Link to comment Share on other sites More sharing options...
GZ_Loach Posted February 4, 2011 Report Share Posted February 4, 2011 You can get heater sheilds to stop fish burning themselves. But the only thing you can do about the bullying is to seperate the fish from each other Quote Link to comment Share on other sites More sharing options...

Kinbote Posted February 5, 2011 Report Share Posted February 5, 2011 If you haven't actually seen any of the other fish harass him, it could be a columnaris infection which will make the fins disintegrate like they've been chewed off, cause red patches of dying skin that might look like burns, and can also make the fish separate off from the rest. It usually infects fish that are already weakened for some reason. If you've got a quarantine tank you'd do well to put him in there, which would also resolve the bullying if that's what it turns out to be. It's very variable in appearance, but check out some pictures: http://www.google.com/images?um=1&hl=en ... 80&bih=959 Quote Link to comment Share on other sites More sharing options...
