tiger tail
 

I have had a tiger tail cucumber for quite a long time but this morning it is climbing on the glass is this normal or not.

I had a pink cuc that sat at the top of my tank for the whole time i had him. I could drop the water level and he would stay there no problems, i couldent even pry him off.

I just thought that it was wierd but he went down into the sand again,mabey he just came out to say hi.

Once in a blue moon I find mine up near the top trying to insert himself into a powerhead but other than that he acts normally.
