I am on about 15 forums, 7 of them are about fish, the rest just show pictures of Beautiful Babes on Corvettes, but I digress, of the fish forums I am on, probably half of the topics start with "Help" spots, dots, salt and pepper, rash, etc. Or something died in quarantine because it was already infected. I think all fish are infected with something when we buy them but a fishes immune system works great, even better than ours.
In the beginning of this thread, I put forth my theories, which are just mine and are just theories but the older I get and the more experience I have, the more I believe them. As I looked at my tank this morning I noticed that not one fish has a missing scale or scratch, not even the 20 year old firefish, although he does look tired.

My mandarins are spawning as are my clown gobies and cardinals. I think my pistol shrimp are to but they spend most of their time in a cave so I don't really know but the male smiles a lot.
None of my fish hide or are scared of me, they just want to bite me which is a healthy sign. Their diet is mostly live worms. Blackworms and whteworms.
Anyone can get whiteworms as they live in dirt and are free. After you buy a cheap starter culture online, they grow and multiply like crazy on just Cheerios. I add some fish oil to Cheerios just for the heck of it and I add fish oil to everything because I think it is a health miracle, but that's just me. I have no studies to prove anything. I also don't know if whiteworms are as healthy as blackworms as I am not a worm expert. One plastic shoebox of whiteworm culture allows me to feed whiteworms every day. If I used a larger plastic box I would have enough whiteworms for me to also have them for dinner. But I don't think I have enough hot sauce to cover the wormy taste or cover the slime factor. :worried:
Besides worms my fish get eith er frozen Mysis and clam. That is their entire diet. The newborn brine shrimp is mostly for the tiny fish and mandarins but they don't really need them.
I also believe, as I mentioned ad nausium, that a sterile tank is not a healthy tank. If you don't believe me, start your own thread, but write it in an operating room. :beer:
