I think we or i need some pics of your scombs and tank and set-up. ^^^ I have tried keeping them with several different set-ups for years and have had no luck. I have messaged several people on here that said they had owned scombs and they all said these same things. I have tried a 55g gallon with normal filtration, A 55g with 2 emporer 400's and a magnun 350 canister. A 75 with 2 emp 400's a magnum and 2 400gph power heads. I have tried keeping them in small 20g tanks with current and no current. In each of these set-up i tried weekly water changes and 3day WC's and the last time I tried 50% daily's with aged and treated water(24hour). I have tried a ph of 7.0 and as low as 6.0 which was a idea from a fellow mfker i still have not had one last for more than 2 months and you have had yours for over a year, so lets see what it takes and lets see a 1year old scomb. thanks alot ----I am being very serious i would like to know how to do it. I have been buying these fish ever since before most people knew about them and they cost me over 100 to start years ago. Now that they are more popular i am glad to see others interested in them and the price drop so much. ---Also I now have a H tat that is doing great in the last set-up posted I have had it for about 3 months.
