What do u think.
gastromyzons are hillstream loaches also as noted in the link I gave and you can keep one. But from experience they are happier in groups and display more of their natural actions in groups. Since they need a highly oxygenated environment higher tropical temperatures don't lend themselves to good benefit for Hillstreams. They will literally sufficate if the water isn't onygenated enough.armadillo said:I love hillstream loaches, but I confuse them with the gastromyzons (butterfly loach). Apparently, it's OK to keep one of them (sorry, dont' know which anymore) in tropical temperatures but they can withstand colder temps. Not much help here, am I?
