I'm been thinking about getting one for months and finally decided today is the day! My girlfriend and I pick one up and its about 3". So here are my questions. What do you guys feed yours so they have a healthy diet? I was planning on feeding frozen bloodworms and spirulina brine shrimp, anything else I should add? I'm going to cut and sand a piece of PVC pipe for it to hide in, does pvc leach any chemicals that I have to worry about? The tank is a 55g and will be upgraded to a 180 in a couple of months. Any other tips to keep my new bgk happy would be awesome!!!
