Ok, fiddled a bit with the flow and i think everything is ok now. They have not figured out the tubes as hitching posts, but i hope they do soon. I added several more than what in the above picture. I also took pity on the little boy and added his beloved thermometer and he is happily hanging off of it.
Anways, hopefully tomorrows feedings will go well, this are a bit bigger now.
And stay tuned for the algae scrubber build!
