Title: Subtropical or cool water tank
Post by: keeshfish on March 05, 2010, 06:53:12 PM
So in the light of soaring energy costs and "saving the environment" I decided my 30gl or 115L tank would be subtropical. This means no heater in summer since I live in South Africa and its pretty warm here in summer and a heater for around 4 months of the year as our nights get chilly in winter. The tank is planted with hardy aquatic plants too.

My tank is 92cm long (3ft) and houses a mix of tropical fish that are cool water tolerant and some true subtropical fish.  Here is the species list:
1 Female blue Gourami
1 juvie female paradise fish
3 buenos aires tetras
3 black skirt tetra
3 albino black skirt tetra
6 assorted platy
5 female guppys
6 male guppys
2 hill stream loaches

All these above fish can survive down to temperatures as low as 18 degrees (Celsius) however I don't want to torture them so my heater in winter is set to 20 degrees.  

Keeping a subtropical tank does have its limitations (like no cichlids for example) however I wish they were made more common to the lay man as it makes running an aquarium even cheaper while still giving you more choice then a cold water aquarium.  Best thing is most of the cool water species are super hardy and easy to look after, also feeding them is rarely a problem as they are all little piggies and in front of the line at feeding time.  Strangely one of my hill stream loaches is so cheeky he comes out when I feed the other fish and starts rummaging around the bottom for snacks and the occasional shrimp or blood worm that lands on the bottom.  He even seems to recognize me as the thing that means food.

I have attached a picture of my subtropical tank.  By the way besides being cheap to run its also a second hand tank from junk mail.  One of the filters (the HOB) is a hand me down.  I run two filters in this tank and change around 50% of the water every 10 days.

Remember fish eat less in cooler environments so these guys get fed a little less then they would in a warmer tank.

What do you think about subtropical or cool water tanks?

just on a side not the guppys have been given to a friend and the platys moved to their own tank.  Also I returned the buenos aires tetras.  Now there are 4 bronze corydora in there and I have moved my tiger barbs into there as well.

I saw your stock list and I was like  :jaw:  But since you moved some, not so much shock lol.  Its a really pretty tank. Are you asking what you should do with this tank or are you asking opinions on cold water tanks in general?

My tanks are all inside unheated. I like your list of stocking. I have black skirts as well, and white clouds, as well as generic platys in the tanks, which range from 67F in winter to 80f in the summer. Recently, I designed a 16 High for native, to our  south east, least killifish, a tiny livebearer.<a href="http://s1049.photobucket.com/user/lv2crp/media/image1%2045_zpsnobsztvk.jpg.html" target="_blank"><img src="http://i1049.photobucket.com/albums/s392/lv2crp/image1%2045_zpsnobsztvk.jpg" border="0" alt=" photo image1 45_zpsnobsztvk.jpg"/>[/url]

Nice Tank Gregg.

Thank you Russ! The tank was done from the ground up including substrate I found on the side of a road, and run through a 2mm colander of my wife's. Just inert sand, but a tiny bit of Thrive and fish waste (and snail), has the stem plants living. I have to give away the frogbit now and then, but those long roots are the perfect jungle for that fish, which lives in such an environment. That small fish has personality and the tiny newborns are just cute, they live well in that mature tank.
