Hi mate sorry to bother you again you just seem very knowledgeable. I sorted the lack of Pygmys by adding another 3 so I now have a group of 9. With 3 bronze corys and 6 glow light danio. My local fish shop recommended a female betta to add to the tank and was wondering your thoughts. Didn’t want to create another thread to bother people so just wanted to measure hereStop. Adjusting water parameters is a very risky and complicated bit of chemistry. What is the GH (general hardness)? You said "generally softer water" in post #1 and we probably should not have overlooked this. You are in London, UK presumably, which I thought has hard water. Can you pin down the GH please?
The iridovirus seems primarily confined to the dwarf gourami, but some sources do suggest it may spread. It really is not worth the risk. You have to consider your fish first.
