Hi all first time post here. I recently got 5x clown loaches from a local fish store. I love the way they look . This ain't the first time I have Clown loach the last time I have 5x die to dirty water like few years ago . But back then I do water change like once a monthes or so. And thats probably why they die. Any ways now I have an 25g planted tank fully set up and cycled no problem. At first I bought 2x from a store which is like 3 cm long pretty small. Then I get another 3 from an old store I always go to which is alot bigger like 6cm one. Those 2 dont seems to get along with the other 3 very well I guess the other 3 must bullying my little one . The little guys always hide some where under my wood during day and some times come out exploring but those big one seems kind of stress and swim all around the tank when people go near they like gone crazy and swim immediately to the back of my tank hiding behind the woods. I have set up an hole with rock cover to previde them dark place to hide during day time but they dont seems to like it much only 1 of those 3 go in there sometime. Any one have idea how to get them less stressed? Oh yea the tank also have 17x neon and cardinal tetra inside before I have these loachs they seems to do pretty well so thats why I thought I can give clown loaches another try.
