see, i think they actually do form some sort of bond. i originally bought 3 white's, two nights later, one escaped. i never did find him. i had another escapee and and after correcting my security issue, found him. those 2 spent about 2 months together until their new tank was done. in the meantime, i had purchased another 3. they were in quarantine for about 2 days, and the other guys were in their new tank when lo and behold, i found my other lost frog. i put him in quarantine with the other 3 guys, mainly because he was so tiny. so those 4 spent a month in quarantine together. now, those four are always hanging out together, and the other two are inseparable. occasionally, the first two will interact with the other four, but for the most part, they have their own little cliques.......LOL

so my answer would be to get him a companion
