:-? My healthy 3yr old betta is showing all signs of illness and and to start with had a white smooth patch on his chest.....after some research and the pet store...I've treated him with Furan 2 for 7 days....this didn't seem to do anything.. so did a couple 60% water changes and put new sponge and charcoal to the filter to remove any remaining meds....still no improvement....it's been 2 days now....and the discolored area looks golden now with some red areas....I coaxed him out from the leaves late tonight and the swim by to say hello seemed to be difficult for him...weak maybe....as this has been going on for almost 2 wks....but amazingly enough he ate 3 pellets while he swam by.....should I treat with Tetracycline?? As there is definately a problem still. Any advice would be great and I will try to upload a pic or two. Thanks for reading!
