So I picked up 5 zebra loach about 4 weeks ago - like the clown loaches (I have 4 clowns); they broke into two groups - a group of 1 and a group of 4 (the clowns are 3 and 1). The single zebra loach likes to hang out in the jungal val. For some reason the jungle val form a massive twist at the top and he hides in the middle of the twist (i keep untwisting it - and i swear he must be like a little beaver at night tying the leaves back together). Is this common behavior of loaches - where one will not hang out with the others - in the case of my clown he would stay vertical in a corner next to the sponge filter - he (or she) eats - if i drop a shrimp pellet in his corner he is quick to gobble it down. Unlike the clowns (which are quite young at around 1.5 to 2.5 inches long) the zebra are near or at adult size.
