So I currently have roughly 100 convicts in my 75G. All appear to be healthy and doing ok, but space wise they do not seem like they are enjoying be crammed in there. Any ideas on what to do with the over population? I hate to cull them, but can't imagine they are having a great time being in such a tight space. Plus I am not happy at having to do water changes every couple of days to keep nitrates manageable.
