Hi everyone,

So I began my first freshwater tank on my own. My brother is a "fish master" and has owned freshwater and saltwater for years since we were kids. I've always helped him but I recently have my first real tank on my own (had guppies, goldfish, cichlids on separate occasions in the past)

I impulsively bought 3 sunburst orange glofish because they were cheap (originally wanted the starfire red ones) before I knew that they were genetically modified zebra danios. I originally wanted the red glofish plus green tiger barbs, but decided not to since my tank is a little too small for the barbs in a few years.

Basically, I would like to get rid of the glofish and get rummy nose and cardinal tetras but I feel kinda bad for wanting to abandon them since I know they are extremely happy in my 20L.

To get to the point, if I decided to keep my 3 glofish, would it be wiser to go with a school of 5-6 rummy nose or cardinal tetras? They're both really peaceful and my glofish are really playful/active and dart around like crazy. The cardinals are beautiful and I know will look great with the contrast of green plants. I've seen some threads of people on here having danios and cardinals with success, despite conflicting info online and from LFS. Any reccommendations? I also have 2 panda corys and 1 white cloud minnow (an orphan I took in from my friend).

Since you are attached to your trio of Glofish (I relate to you), consider getting three long finned zebra Danios so they can school comfortably. Once they are settled you could probably add both (Cardinals and Rummy Nose Tetras).

Keep in mind that your tank is quite new. As far as I know Cardinals and Rummy Nose Tetras are considered today as delicate fish that need a stable or mature tank to succeed (they used to be considered as hardy, but not anymore).

I don't want anymore danios...I actually prefer the regular zebra danios over the long finned ones. If I keep these 3 glofish I can still have a total of 12-13 fish since my tank is a 20L. The dimensions are 30x12x12. What's the rule again? 1 inch per fish? But then I need to assume that they can all grow to about 2 inches...


So does 1 white cloud, 3 glofish, 2 panda cory, and 6 cardinals sound good? I don't have room for anymore, as much as I like balloon prystella tetras and rummy nose tetras...Or can I have some more?
