if you want get a piranha then you can go by with a sanchezi or someone will say elong.
but elong is fast swimmer so a longer tank will probably be better or you'll need to add a powerful power head.
if you want something else, then you can put a rainbow wolffish in there

I must be confused as to how to measure a fish. Mine is nearly 7 inches and looks fine in his 25 long. He doesn't act cramped, doesnt act depressed or lowly all the time. I see nothing wrong with him. Wierd.

you have a 7" rhom in 25 gallon tank? Pics?

how can we tell a fish is happy or depressed? sometimes we can't even tell if a human being is having any mental problem.

Can you put a fish in a small tank, of course yes. would that be in the best interest of the fish? I'm afraid that I have to say no. We've already taken the fish out of its wild home against its free will, why not give it a proper glass cage to call home for the rest of its imprisonment?

all I'm trying to say is if you value your fish and would like to provide it with a proper long term home, a bigger, wider tank will be required.
in the end, it is your fish, your call. just remember, all the crazy ppl here providing larger than average tank to a solo fish is not for no reason.

all tanks are too small for all fish.

what do you think about 180g for one neon, barely enough? or I need bigger?

elong is too big for a 55G (4 ft)

one dart and the fish will bump its head

well I mean there are tanks that are more comfortable for fish than others, but even that one neon probably swims a lot farther than 6' or whatever the standard measurements are for a 180g tank in the amazon. Even the smallest fish roam farther than the largest tanks in the wild. That's all I meant.

You also have to consider how your tank affects the growth of the fish. Those monster rhoms you see occasionally are definitely not raised in small tanks like a 55g.

I would keep it in a 55g till it was about 5" then move it to at-least a 5x2x2 that is heavily planted so it doesn't look boring and also to help remove some nitrates.
That way it will grow faster and larger.
