Suggestions For My 45gal Community Freshwater Tank?

  Despite everyone in my tank being adult size, it's looking quite empty! I wanted to add a Yoyo Loach but on research they need friends and will probably nip at my other fishes' fins.

I was thinking of some kind of bottom dweller or maybe another school of fish, like glowlight tetras. Or something red. I'm open to suggestions, thanks.



My tank:

45 gal (3 foot), 2 canister filters, weekly-fortnightly water changes

Here's an old photo of it (that Amazon Sword has turned into 8 now, lol. Lots of caves. No I don't have guppies anymore): http://sphotos.ak.fbcdn.net/hphotos-ak-a ...

* 2 Cockatoo Apistos (had three but one of the females died ...)

* 2 Bolivian Rams

* 5 Rummynose Tetras

* 2 Peacock Gudgeons

* 1 Male Betta

* 1 Longfin Bristlenose Cat

Fish have all lived peacefully together for a year. pets question and answers,www.5d2d.com



Thanks for your help!:)
Instead of the yoyo loach, how about a shoal of java/black kuhli loaches?



Glowlights are a very good choice.



For something red, harlequin rasboras would be great.
If you're after something red, what about a shoal of Harlequin Rasboras? They're pretty easy to find and relatively hardy, and should be fine with your other fish. They are mid-top dwelling also so will help fill that space.



You could try 6-8 in that size tank, they get about 1.5 "and are peaceful.
