Hey guys, I'm restocking my 2.5 gallon Pico and am trying to decide what to add next. Current inhabitants are a Greissenger Goby, a Tailspot Blenny, and Bumblebee Snails only. I found a small Sea Apple about 3 inches going for $24 and since I've never kept one before I thought it might be an interesting addition. I also have a love for mini Scolys which run about $14 each. The only reason I'm hesitating to choose like 3 of them is because the current ones in stock aren't particularly shocking in their color variations and new ones show up frequently. What would you guys choose?
