My only concrete decision right now was in having some inverts so finding fish that can live with them may be more important to me. I modified my GH to be around 20 dGH with a shrimp supplement (though I have no shrimp I was just testing it out). I may try to reduce that a little bit. The pH in that tank was 7.8 the last 2 times I checked it and that water has been in there for almost 2 weeks now.

I think this looks fine for Harlequin Rasbora and shrimp. I think I will take the Cardinal Tetra off my list.

I recently witnessed some very extreme aggression with my Orange Dwarf Crayfish (CPO). If he saw me approach the tank, even though I'm 1000x his size he will come to the front of the tank to meet me with claw drawn and then start clawing at the glass with all his legs and claw! I think he would be dangerous in a tank full of shrimp and fish. He will get a little bigger than the shrimp. He's a slow guy, but I still worry shrimp wouldn't stand a chance with him around. He is probably going to stay in his tank unless I get a 4th tank I may make it into a crayfish tank.

The crayfish behaviour might be linked to food; seeing you probably signals food to him, as it does to fish. But I would think any crayfish a menace to live fish and shrimp, notwithstanding.

The pH will not naturally lower without fairly significant biological action. For example, most of us with planted tanks never vacuum the substrate, but leave all the organics there so the bacteria can break them down into much needed CO2 and other nutrients. Another issue I don't know is the buffering capacity of the additive you are using. There is a very complex set of biological and chemical interactions ongoing in an aquarium, and every substance added from fish food to water conditioner to supplements will affect all this.

If the GH is up at 20 dGH I would caution any soft water fish. About the hardest water we approach in the hobby is that of the African rift lakes, often called "liquid rock," but the hardest, Lake Tanganyika, is only 10-12 dGH. The pH is correspondingly high too, up to 8.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

I can change some of the water out and get it down somewhere between 10-15dGH that the shrimp need. From my research Harlequin Rasbora can handle that fine. The pH never changed after adding the general hardener even after a few days. I added to much of that shrimp supplement the first time - which is good why I tested it on the tank without fish.

So to recap: 7.8 pH, 10-15 dGH, 80F. All of this seems to be in the range of Red Cherry Shrimp and Harlequin Rasbora. I will go with this and maybe spend much more time deciding on a second species of fish. I still need to redo my plants (wasn't happy with it) with different ones and give the current ones away. So still have a lot more time before I can even order fish!
