It is only my opinion. They do have feeders btw but they are treated well. I just know that if I knew the fish was going tpo an usuitable home that the nowner had no intention of upgrading I could not sell it. I was using the zebra danios as an example. I was saying if you get crazy like telling people "Im not selling you these danios because you have a 20 tall and not a 20 long!" I think that we, as hobbyist, need to be willing to make the decisions that the other businesses arent. If we are willing to sell fish to people who are going to keep them in tanks way to small are we any better than the people who sell bettas to people in bowls (Whom many people on here express deep dislike for)? I am not saying that if a person has a tank that seems slightly to small that you shouldnt but if it is horribly to small then are you wanting that to be the way you make money? By selling animals into torture homes? I mean if somebody with cichlids wants to buy a couple rcs even though you tell him they will be eaten then that is their poragative. The animals wont be tortured. Just swallowed quickly with no cruelty.
