Have you heard of goldfish fighting to death during a spawn? Here is my story. I have a 4000 gallon goldfish pond that keeps 12 goldfish. 6 of the goldfish ranged in age from about 9 to 3 years old, the other 6 are 1 and 2 years old, all veil tails, born and raised in the pond. Of the 6 involved in the spawn, there were 2 females and 4 males. Over a 2 night period, the following morning all 6 had significant fin nips and bruising, with 5 of the fish dying over a 3 day period. My impression is that they died from exhaustion and deep internal bruising. The water condition is good and there are no animals involved, no diseases. The 6 juvenile fish are in good condition, as though nothing happened. Any insight would be helpful.

Hi I'm fairly new to having fish. I have a 10 gal. With 2 comet goldfish, 1 calico ryuken, and 1 red cap oranada. I know I need a bigger tank, I will be getting one soon. All my fish are showing signs of ich. I believe it is because of the way I did my last partial water change. My oranada was not the original. The first one I had died about a week after I introduce her to the tank. But I believe I caused her stress (I did a partial water change right after putting her in the tank), which in turn gave her ich. I did not know it at the time, because she was the only one sick so I just attributed it to her being new. But now all my fish have ich (I never changed or treated the water after my first oranada died). Again, I didn't know she had ich. What can I do now? I just did a full water change and bought Jungle brand ick attack. I added aquarium salt to the water as well. I have been treating for 24 hours now and my 2 comets appear to be rid of the spots, but continue to sit at the bottom of the tank most of the time. The ryuken who appears to be infected the most has been the most active. How long does ich take to clear up? Any suggestions on what to do different?

Hi - I have a hippo tang about 7 inchs - lately she swimmes up and down the tank in one corner she looks as if she is stressed. Because she has an 180 gallon asquarium to swim. About a year ago we lost our clown fish to slim. Hoping to replace them, should I buy them in pairs. Wondering how offten should we change the water and what percentage.
