i finally decided to clean up the whole tank and filtration to beging a new tank all over. seems the new tank is a new graveyard for my fishes. i lost all the king tiger pleco L-066 (which were the most expensive ones)
i joined all the remaining fished with the goldfishes. seemed they are doing better to consider their is no meds in it or any treatment, temp at 76 F. i'll observe them for 1 week and i'll have my total death count on them.
seems the tank is a bad luck tank
never happened with my smaller tank when all where their with the goldfish... always did the way i'm doing now. are my fish lonely because the goldfish weren't their? but they were too many in a 30 gallon tank. kinda weird to think that way.
need to get my new tank blessed by a priest
thank you for all the help that were given... highly appreciated!
