I need a suggestion for an algae eater

29g planted CO2 injected tank
pH 7.0
kH 6
yeilding 18ppm

water changes every 2 weeks still gives me a good bushy layer of algae
and it's not a nuisance, but back to the question, I've been letting it
get that way somewhat on purpose... it's a growout tank of sorts, 7
kribs total, 2 adults, M-F, but they won't breed. The other 5 kribs
are babies from another breeding pair, in another tank. They all range
from 1" to 1.75". Also in the tank are 11 1" long lemon yellow labs...

I need some bottom feeding algae eater to combat all the algae and help
clean up the bottom where the plants aren't sticking out of it.

Otos don't like this tank... Ramshorn snails won't multiply enough to
help, and I don't want another monster pl*co, can't get
bushy/bristlenose. Can't get algae eating shrimp locally, but can get
golden and regular chinese algae eaters and siamese... which are
better, more efficient, etc...

in other words, I miss hearing you guys debate this stuff, just wanted
to stir the pot and yes, I am sincere about the question...
yer ole buddy...
