smallest tank size?

my brother loves dendros and duncans he wants to make a tank for just them but he wants it to be as small as possible because he lives in a closet sized apartment. i told him i could spare a frag off of my colony for him to get started. so how small can he go? he is perfectly fine with doing small daily water changes so i dont think he needs any crazy filtration if much at all.he will not be keeping any fish or other coral just the frag i provide and i can frag it when it starts to get to big.

 

and mabe a/afew small hermits/ snails

 

there ar some wicked awesome 3 gallon picos i love. there like 50 bucks. then you could do LED lighting with it. that would be nice.

 

I say get him a ada, gla or Mr aqua rimless tank

 

his initial idea was to put it in a big glass sauce jar i have at my house. lighting isnt a concern because they arent photosynthetic. thats part of the draw to him.i saw hemispherical tanks that hang on the wall which i thought might work awesome with limited space.

 

i just got a CPR Pico 3 gallon and am setting up rock work right now. Pretty cool little tank!

 

well i think 3 gallons mite be a bit much his apartment is small.... probably less than 100 sq ft bedroom/kitchen and bathroom and closet.i found afew 1/2 gallon tanks and afew 1 gallon tanks .i think this mite b the route we take. just need to find a tiny power head/pump lol

 

Duncans are photosynthetic.

 

I think a half gallon tank would be to small, even the one is pushing it. Unless he built an auto top of system. The swings would be way to great for the duncans. And if you were going to build an auto top off then its worth it to just get the three gallon.

 

tushe on the top off i wasn.teven thinkn bout that.ok ill hafta recincider my ideas i think
