after i acclimated my convict to the water i let him in his new hour later the blue gourami starting invading the convicts space,following him,just being a nuisance and somewhat aggressive. not long after this clip the convict got fed up and gave him some nips to leave him everyone stays clear of the convict,and he doesnt try harassing the other fish 95%of the time and when he does the others run and there is no pursuit.the convict even made friends with the plecostsomas,they share the log hiding spot together its pretty kewl.convict keeps the other fish away and the pleco keeps the hiding spot clean for the convict.
