Our
red tail shark died

The tank looks empty without him-he was the biggest fish and had such personality.
Were going to wait a while, but I decided to search out some ideas- we would like a center piece fish and need some suggestions.
Not another red tail shark or a rainbow shark.
We have a peaceful commuinty freshwater tank and would like a fairly active fish that doesnt hide all the time as the 'center piece' fish.
We got three upside down catfish a few weeks ago and they are fun to watch, but rarely come out of the castle.
I like the kissing gourami's, but know little about them.
