I've never been good with fish. I kill goldfish when I'm trying my hardest to keep them alive. Recently, my dad was diagnosed with stage 4 lung cancer & is now on hospice. My sisters and I bought him a Biocube for Christmas (before he was diagnosed), and he felt like he's wasn't going to get to see fish in his fish tank. I'm trying to make it happen, and so far....so good. At this point, we have 2 clown fish (his favorite), a sea anemone, and 14 hermit crabs. I have so many questions that come up, and don't know what website I should trust....I'm hoping this will be the place to be...
