Yes, but it depends a little bit on what fish you want to keep
You can't keep sea creatures in a freshwater tank!
In your case, I would get a Ancistrus spp. (type of catfish), several of these don't grow larger than 6", they're peaceful and excellent algae-extinguishers. The L144 is even attractively coloured. They're night creatures, so you may not see them a lot during the day. They need vegetable food and fibers, so if you run out of algae you will need to feed them with something else otherwise they may start on your plants (assuming you have real plants). They like cucumber, or sinking green tablets for vegatarian catfish.
Another option is to keep Otocinclus spp., also a small type of catfish (2-3"), best kept in a group. They're a lot more active than the Ancistrus, but less effective in eating algae.
