I found a 5-gallon tub! I put him in a cup to take a better pic... I also don’t have a spare filter. Where I live, it's always around 70-80 degrees... Do I need a heater too? What should I do?I imagine you'd need something bigger, mainly because of the size of gouramis. Think 5-10 gallons and leave him in there for around two weeks with a filter and a heater.
Also, can we get a picture of the gourami? Sometimes people confuse columnaris with ich.
Ok thank you!!Actually that temp is fine... you won't need a heater. You do need a filter as you aren't doing a bath, but you are keeping him in there for a few weeks.
Yep, I think that is ich.
