Filtration for 35g hex tank

Hello TFK!

I've recently received a 35g hex tank and I'm curious what my filtration options are. The tank will be pretty exposed on all but 1 side and each 'side' is 11.5 inches wide. Tank of course is a 35g hex. Any info or thoughts would be greatly appreciated.

First off, welcome to Tropical Fish Keeping forum. Nice to have you with us.

Filtration should be based upon the needs of the fish that you intend to house in the tank. Not all fish need the same amount of filtration and associated water movement, so this is important. Also, if live plants are intended, that makes a bit of a difference.

Generally: An internal filter such as one in the Fluval series by Hagen is one option. A sponge filter would work if you intend live plants and forest-type fish. A canister would be better if more water movement is needed, as for larger fish (though not too large in a 35g) or fish coming from fast-flowing streams.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Thanks for the response! The plan is probably some small schooling fish and some Java Moss. I'd say I'm a minimalist when it comes to the tank decorations.
