ok so i just set up my new ten gallon tank for my one betta. i have the filter and heater and even some live plants in there with conditioned water and everything.
last night was his first complete night in the tank i wake up this morning and he looks horrible i dont know what to do it looks like he is developing fin rot but i wouldn't know why cause the water should be very clean still. i have a couple pics one of him in his bowl the first week we got him and now we are on week two and hes in a bigger tank by hisself and looks bad. i am confident someone on this site can help everyone seems pretty knowledgable the pictures aren't in the correct order im sure you can see the difference its pretty drastic.
