I can think of a number of catfish/algae eaters that do fine solo but none of these would work in a 5gl as it's much too small. If it were me (and it's not!) and if this 5gl was an established tank with live plants you could do a trio of otos. I keep a betta in a 6gl w/ a trio of otos but my 6gl has been set up for nearly two years and is very heavily planted. You could also look into dwarf (pygmy) cories but they also need an established tank with spot on water parameters. I'm not a snail person but I believe there are some algae eating snails can live happily with bettas, provided it's a very docile betta that won't attack their eye stalks.
