HI. Recently got a male betta (named Salvador) 4 weeks ago, who when I first put in my tank was so very happy, blowing bubbles. Then noticed he was spending lots of time at the bottom and colour fading.
I bought him a heater and thought that would make a differece but not really. He sometimes lays next to it, but then goes down again. He was such a active fish now nothing. His colour has also faded and is not eating.
I have just done a 100% water change and have started the heater on a lower temp to build up gradually to 75F.
Is there anything else I can do?
