Catfish to eat brown algae off of glass

    Hi. I have a 16 gallon tank with platies and amano shrimp. The water parameters are good (ammonia 0, nitrite 0, nitrate 5) and lighting is on a siesta schedule (6 hours on, 4 off, 4 on). Between the low nitrates and amanos, virtually all of my algae is gone, but I still get brown algae on the aquarium glass. It is very difficult to clean because the amanos chase the brush I use, so I have to be very careful not to hurt them. Question is what catfish would be good at eating the algae off the glass? I like corries but am not sure they would fit the bill. I know snails would work but my daughter just doesn't like them. Any suggestions would be much appreciated.

    I have had a problem with brown algae in a couple of my tanks with otos so I wouldn't recommend them. I have no algae issues in the tanks with a bristle nose pleco so that's a good option or a couple nerite snails.

    Cories will not eat algae off the glass.

    For my oto tanks, I just manually clean it as it crops up.

    Cories won't eat algae at all.

    They will graze algae, but not enough for removal and never off glass like an algae eater does.

    My mystery snails take care of most of it. I still just wipe the glass once a week with a clean wash cloth. It only takes a few minutes.

    Corys are 99% carnivores. They will scavage the surface.

    There aren't any fish that are appropriate for a 16g that would eat algae and I agree that corys aren't algae eaters.

    If this is new setup, diatoms will go away in time. You can just wipe them off yourself. :)

    And it might be helpful to reduce your lighting to 4 hours on, 4 hours off, 4 hours on. 10 hours on is still a lot.

    Brown algae often is caused by low lights.

    But leaving the low PAR lights on for extra two hours won't be helpful if it's still such a low light, right? Those extra hours might allow other algae types to grow. A better light (with a higher PAR value) would be better.

    The first I don't know, the latter I agree with.

    I use 2 lights in the tank, a 6700k T8 fixture (sold specifically for plants) and a Finnex Stingray. I don't have the ability to measure PAR but am guessing I'm in the low to slightly intermediate range.

    You're in the low light range still. I'd decrease your lighting to 8 hours still.
