Hi hope I don't get in trouble for posting so many questions.

I was wondering if it is okay to have algae eater fish along with the other fish in a tank or fish pond to help reduce algae?

Will the bigger fish eat the algae eaters?

Once everything is well established, algae shouldn't be too big a problem. Initially you will get the pea-soup effect I am sure. A UV filter makes short work of that type of algae if you have one, but it usually improves over time with careful nutrient monitoring anyway.

In a pool of that size, you would need an army of algae eaters if you went that route, and they would cost much, much more than your other fish you are raising (unless you raise koi). Hyposomus Plecostomus are commonly used in aquariums, but they only eat the algae when small, and once they get bigger (and they get much bigger), they go for the plants. Same with the Gyrinocheilus aymonieri. Primarily, algae eaters require warm water and wouldn't deal with the lower winter temperatures. Depending on the species of fish you are raising, they indeed might eat any algae eater as well.

Although they are much maligned, pond snails actually eat algae as well. Given enough time, most larger ponds seem to get them anyway, mine always have. It is not a bad idea to ensure that you get disease free snails of your choosing to get established in the pond before others establish themselves. Many types of fish also enjoy a snail snack. Some species are even good for people to eat. Yabbies I believe will also eat algae on the bottom, but wouldn't be suitable with a gravity fed bottom drain like you probably have.

Probably... but it might depend on the fish.... in aquaponics, while you may end up with a layer of bio-film around your tank... you shouldn't really have any algae as such...

It should be noted that if you are in an area that can handle tilapia they eat algae

HA, No Tilapia allowed in Aus :)

Look up Gibbiceps catfish.
They grow to 60cm and will handle temps down to around 18.
Mine is now at around 35-40cm and loves algae. It is one of the few pleco catfish that will always eat it.
And they are tough enough to stand up to bigger fish like Barra, they come with armour plating!

There are also always some availble as people buy them for there 3ft fish tanks and realise 6 months later that a 30cm long fish just doesnt fit anymore.

You will need somewhere to house them in winter if you live in the metro area.

Most of your local fish shops will have them if Gumtree doesnt.
Dont be surprised to pay $60 - 150 for one fish at around 25cm+
