i had a few fish die a few weeks ago and thought it was time to add some new ones and they are a little bit smaller than the ones in there but the old fish have gone mad i have added new fish before and this has never happened the biggest one seems to have gone twichy any ideas and if anyone wants a big blue stripy African Cichlids who needs taking down a peg or two let me know as he seems to intimidate all the other fish till they die and not sure what to do with it so any good home feel free to email me
