weather loaches are my favorite,i have 4 in my 55g there a hoot to watch,especially late at night when the lights are out is when there the most active.one paticular loach goes so fast he skips across the top of the water over and over(i think this one loach needs to be in a bigger tank :/ my tank is over 4 feet long and it takes him like a split second to reach the other side .its really cool when they swim together weaving in and out of eacher other.im pretty sure there happy in there 55g
the first loach i got is about 6 inches ,i named him mr.wiggles
