Hi,
I recommend starting a thread with your egg questions because I do not have experience breeding them.
I kept them in a trio for several months and would lose one now and then...
I now have two foursomes and will be adding two more of each.
They are much happier this time, and more active. Here is what I changed:
Added driftwood, switched from gravel to sand, used real plants rather than fake, used a shorter tank so they can swim up to the top easier (previously used a 35 hex), food is very diverse and high quality.
Please pm me for more details if you have questions!!
