just a quicky...

I would say no. I say this bc Red Tailed Sharks tend to get aggressive to fish that are of similar shape and size to them. I also say that the Clown Loach will need a larger tank when it matures as they get very large.
 
ye but it takes like 15-20 yrs for them 2 get that big. im not gonna keep em that long! waddya suggest then 1 rd tail shark? or 2 clowns?
 
Flagfish,

I suggest no clowns. Clown loaches are schooling grouping fish and need to be in groups of three or more, although I think they should be in schools of six or more.

Cripes, I can't even imagine any of my 3" clowns in a 45g. They would go nuts. Sure, it may take them a long time to get to 12", but it doesn't tank THAT long for them to grow from 1½" to 3". I've had mine 5 months and they are in a 75g. Next year I plan on a MUCH larger tank for these guys.


My 2 cents

so a single rt shark?

I think a single red tail shark would be fine in a 45 gallon tank. The profile here on AC says a min of 25 gallons. Just to warn you though, red tails can be aggressive and nasty. My brother has one that goes after his tetras constantly. That guy is just a bully. He seemed to get along ok with with the gourammi's but they are a lot bigger than tetras. And he has gotten nastier and more agrresive as he has gotten older (and bigger, close to 5" now)
 
I agree with the nasty part. I got rid of mine at 6 inches bc he was beating up his tank mates. He would actually leave bite marks on them. It was horrible.
 
Depending on what you plan on keeping in the tank with Red Tail Shark, will determine if he is going to be suitable at all for your setup. Size wise he would be fine in a 45 gallon.
The clowns are not an option for you for that size tank. They are schooling so would need to be in a group of at least 6 or more and they grow large. I have 8 of them in my 250 and I've only had them a year...they're all pushing 8-9 inches each!
