Hello everyone! I just added my first livestock this week to my aquarium (about 5 snails and 6 hermits) and put some algae tabs/dried seaweed to feed them. I noticed that the substrate is pretty dirty from the algea tabs and my few hermits seem to be more interested in the LR than the substrate. I was wondering if adding some more clean up crew to the tank would be a good idea. I was looking to buy a crew for a 30G tank since my 72G in pretty new. Any advice? Thanks everyone for the continued help!
