Yup. Corys are great, they stir things up on the bottom and leaves so the filter can get them. They are also very active, and I think cute.
Personally, a Beta would be a nice centerpiece fish for a tank that size for me. Overstocking is not worth it, ever. It only brings heartbreak and sorrow.
I am going for more of a vibrant color scheme for this tank, hence the initial stocking selection. However, I'm posting up my plan because I want to make sure it's copacetic prior to pulling the trigger and am glad I did because I'm learning a lot.
I chose the betta due to the suggestion of my LFS to help cycle the tank. I think the little guy's personality is pretty cool, so there's no way I'd take him back. He seems way too happy in his new home. That said, I don't think he's enough of a focal point to be considered the "center piece" of the tank. I'm going to keep stocking a few cardinal tetras at a time and just see how it is all coming together once I've got a total of 8 in there. Right now I've got 3.
Don't be sorry about the questions! Its awesome that you think I am knowledgeable enough to answer them for you.
The reason I put cories instead of rummynose because cardinals and rummies school kind of on the same level in the same kind of way. Plus they both have red in them. So cories dwell the bottom and keep the substrate fresh and turned over and add another dimension of fish to the tank. But really for your main schooler you can choose rummies or cardinals, whatever you prefer, then add a school of cories instead of another tetra. Which looks better IMO.
2 GBR or BR(same thing I think?) is what you should put in a 29 because they are cichlids who do well in a male-female pair and fight with other pairs unless your aquarium is about 50 gallons or more. This is what I would do for a centerpiece.
Not sure about the Hatchets. Stock them at the very END and decide if they would be a good choice for your tank. Also stock them last on aqadvisor and see what it says. They are great jumpers and might want more room than a 29g. Not sure though.
Clean up crew would probably be amano shrimp. They are awesome. Maybe add some nerite snails for the glass too? But i never owned nerites so I'm not sure.
Hope I helped a little.
You're clearly a lot more knowledgeable than I am!
It makes sense about the different "levels" of stocking. That's why I liked the idea of the Hatchets because they are a top dwelling fish. As far as a bottom dweller goes I'll look into cories and see if there are any other cool options. I was thinking the rummy nose would be cool to have with the cardinal tetras because there would be 2 different schools hanging around, but I'll put some more thought into it.
I'm not worried about jumpers because the tank lid is secure with only a small gap for the filter. I think my LFS stocks amanos, so I'll double check tomorrow when I go back. I looked up nerites and it says they are marine, is there a freshwater version I just didn't see?
When I looked up BRs, there were both GBRs and BRs. The GBRs seemed to have a little more color, but it may just be BS. My LFS has BRs and they are pretty cool. Like I said, I'm going to do some more research and put some thought into this. I have time since I'm only stocking a few fish at a time.
