The best way to deal with a tank bully is to isolate the bully in the tank (use something like a breeders net) for a few days and then release the bully and see how they get on.
Another option would be to return the fish getting bullied and get another one.
i know it works for shoaling/schooling fish, but how would adding more guppys work out? some fish tend to be less aggressive when there is more of the pack to keep eachother in check
Yeah I would like to add some more but think it may be too small. Would ideally like to have 6 and a shrimp or 2.
Tank is going well! Looks really nice too the lighting and hidden filters and that.
The 1 that was getting bullied last night was lurking in 1 place for ages having a little swim then back to its place. But today he looks a different fish. Swimming everywhere and with the other fishes. Hopefully it's sorted out now
