What type of marine aquarium are you thinking about setting up? What are your specific concerns? Just cost, or time/energy as well? Have you ever kept a marine aquarium? Do you know any one who has? Do you have good local support via a reputable LFS or club?
hmm. where to start..
ok. I don't know what kind of marine tank. I'm not sure that i need
a fish, or many fish.
Of course, i've just picked up an oceanic bio cube 8 gallon which appears to be designed specifically for reefs. (which might affect initial investment. it appears that there are some accessories i'm going to want to go with it, but it is a solid foundation to start with) I am definitely concerned about cost, my LFS is GREAT about salt water support (and support in general, the owner is a marine biologist and has several strong enthusiasts on staff) but they also appear to be quite expensive, unless i am mis understanding what i am buying.
if i do go marine, i am going to need to wait quite a while i think to get stuff. I am not always a very patient guy.
another thing is maintenance. Part of what i like the most about my planted tanks is, once they are established, i can let them go for a couple weeks, minus food for the occupants, and everything is typically unchanged when i get back. i have low tech, over filtered tanks for this specific reason. the plants might be a little yellow, but a little attention brings them right back. i don't think i could get away with that with a marine tank.
that said.. all the little fauna of a reef tank interests me. all the polyps and anomenes, etc.
but i just dropped 150$ on a new freshwater setup, plus bought the second tank (originally with the intention of making it a shrimp tank, which it still might be!
) so money would be one of the primary concerns!
