I never wanted shrimp I could not eat with a bit of cocktails sauce. And then I became friends with Rachel O. aka Inverts by msjnkzd.
She got tired of hearing me say shrimp were food for my fish and and I got tired of ticking her off when I did. So, when the current fish in my 5.5 planted tank died, I got some red cherry Neos. More fish which did not eat them went into the tank and ultimate,ly they too were lost. I was going to take he tank down when I realized there were a lot of shrimp in it.
Fast forward and friend on the other coast needed to close down some of her smaller tanks and needed to adopt out some small fish and her Blue Dream Neos. I agreed to help her out. They went in a heavily planted 15 gal. with a few amanos, and a few dither fish. Today the dithers are white clouds. Also a small albino BN went in as well.
Over time the shrimp multiplied and I began to sell them one a month at my fish club's regular auction. But the reproduced faster than I was selling 24-30 each month. So when a well planted 29 gal Q tank was finished doing Q, it became a permanent tank. So I dropped about 15 =20 of the blue shrimp into it. It has a a few CPDs and recently some Neon tetras bred in Israel. It also has a young albino BN.
I tried counting all the blue shrimp in that tank at feeding time recently and stopped when I hit 100

I have already sold about 30 chrimp fromthat tank.
I have had amanos in a few of my planted tanks for going back to about 2005 or 06. I got them as imports for really great prices. However, all good things also tend to have a bad side. With amanos it is that they will eat meat as they are omnivores. This means they will eat fish eggs and even fry if they can. They will eat various fish floods including flake.
I had that 15 gal. above years before with a lot of plants and U had a pair of BN in it. I also had a bunch of amanos. I would wee the pelcos spawn, and the eggs in the cave, Then I would spot a few babies out and about. And then suddenly there were no babies. This repeated itself a few times and figured out it had to be the amano shrimp eating the fry as the parents do not do that. I did not mind as I already had too many BN.
So aside from finding the shrimp can be fun to watch at time, they also cover the cost oc my almost 50 mile round trip to the meeting as well as anything I might buy at the auction. I recently started to donate another 30% of the auction proceeds to the club on top of their regular 20% cut.
So, eeven though I never panned to breed shrimp, I just sort of fell into it. Considering my hobby costs overall, I am not getting rich from shimp. However, I am also having the same thing happen with assassin snails which I got to hand a pest snail problem, Assassins sell as well as the Neos.
