I've started up the Pico tank I won from the recent @ESHOPPS.INC and @WWC giveaway. Went with a simple bit of Marco rock and live sand, the plan is to get through the initial dino phase and start adding livestock with the first signs of green algae. This tank is in a research lab at a university so we plan to keep some curiosities including one or two macroalgae specimens and a lettuce slug, with maybe a snail or two as CUC. Some folks suggest that a tank this size could be suitable for a tiny goby but I'm not sure about that. Since this tank is in a workplace it would be hard to feed over the weekends so I'm leaning against having a fish, especially In a tank this small. Looking forward to add the RFG from @Vivid Creative Aquatics that they so generously offered to the giveaway winners.
