the bog wood was from when it was in my main tank before i rescaped it, before that it was in brothers other tank so no worries there (not the original tank my betta is now in but the one after that).
The heater is only small and i have a thermometer in the tank so i can keep track of the temp, to be fair i've only seen my heater switch on once.
The yellow/tea stain water is from an indian almond leave ( put a new one in when did my last water change), maybe i should take this out.
i left 48 hours (ish) before changing meds and did a water change, think it was about 40-50%. the filter is s small HOB borrowed and has no carbon bits in etc.
i'm completely stumped on what to do to be honest, the only thing left to do is stop my current med, do a full water change and start on the internal bacteria med i have bought.
the latest pics don't really show how thin he has gone in the body, i noticed late last night when he faced the other way that his other eye is a dark colour, with a dark iris, something Wilder asked and i initially said it was white, as you can see in the pics one eye is white with a black iris but his other eye is different.
costing me a small fortune to try and get him better, if he pulls through though it will all be worth it.
thanks
