New Tank advice?

[Novelistnotion]

I have a 29gallon that has previously held three goldies and a pictus catfish. Obviously overstocked, cramped and unhealthy. Just transferred all four fish to better homes.


I want to try some tropical fish in a planted tank, and learn more about proper care of an aquarium. My sister wants to get glofish and I have done some research which basically says they are the same as zebra Danios, so I assume they will be fine in the same conditions.

I was thinking of black sand, with a good variety of plants, six or so glofish and some other varieties as well. I obviously don't want to overstock again, or add fish that won't be compatible. I was considering mollies (is there a big difference in the types? Can you have black and dalmation, for instance? Would two males or two females be okay if I don't want a lot?) What other fish would work? Are there any I should absolutely add for tank health and community?


Planning to reset and replant with new substrate and cycle things for a few weeks before adding fish. This will be a bit of a new experience for me, as we never really had a very healthy tank before and I don't fully understand the process.

Are there any immediate problems or issues with my plan? Anything I absolutely need or should be aware of?

I'd go with a tropical, community tank as well for that size. Heaps of options.

You should try tiger barbs. They are a blast to keep and look amazing. You should also try rainbowfish, but be careful with cross breeding

I'd think a 29 would be too small for both those. The OP might look at platys, which are colorful and ideal for a 29. Just be aware that any livebearer group that has both males and females means you *will* get fry.
