Glad you could join us.
I agree with Autumnsky about the plecostomus. In fact, a 54 ltr is about 15 US gallons. I think even the smallest pleco is too large for that. One or two otocincluses would be a better choice, and they'er cute, too.
Neons are wonderful fish, and that tank will let you keep a small school. They can be delicate though, so you might want to consider a hardier species, such as the glowlight.
And feel free to ask questions: We're here to help.
