Lionfish,
Do what we tell you to do -- sell the 125 and start working on the 40 gallon. As I said many times before, you cannot afford anything for your 40 gallon. I can imagine what a mess you would be in if you even attempted to setup a 125 gallon. You say you have a paying job, but I simply do not understand where this money is going?
What I would do:
1. Sell the 125 gallon.
2. Save up for some good lighting -- maybe 4x 65wt Power compacts, or 4x 110wt 48" VHO's. What do you do in the meantime while you're saving up? How about you read on this board. Don't ask any questions before doing a search.
3. Once you've saved up and have some knowledge, buy some good lighting.
4. Buy a good skimmer, as well.
5. Possibly try some less-colorfull mushrooms and see if they survive.
However, I have a feeling that Lionfish simply will not listen to what he is told. He listens to only what he wishes to hear and ignores everything else. He has stated several times that he does not listen to his LFS as they do not know what they're talking about, however he seems to post later and say "But the petstore said it would work...".
Lionfish,
I've simply had enough. We've all tried to help you, now it's up to you to help yourself. You're the only one who can choose to listen to our advice. Either take it or ignore it. If you choose not to listen to us, then why even bother posting? You seem to know what's best, anyway
Likely you want attention from your posts, which you seem to be getting. But is it really worth killing innocent creatures for? Maybe it would be best to simply start this hobby at a later time in life, when you have matured slightly, and learn to listen to what others have to say and accept it. One thing I can gurentee, if you do not listen to us now, you will eventually learn the hard way. Trust me on this one.
