Plants for unheated tank

[bozco]

I have a small tank that will soon house four white clouds, but I don't know what kind of plants will do well in the unheated water. During the night, in the winter, the water will cool to around 18 C and suring the say hits around 22, in the summer these temps will rise to about 20 at night and 25 during the day. The room is really affected by the outside temp.

I have plants in my tropical aquariums but don't know about cooler temperatures. Pretty new to plant keeping period.

I know egeria densa (anarchis I think it is called) can take really cold temps, definitely into the 60s.

My brother-in-law was growing Pennywort in the basement in a goldfish tank somewhere between 55° and 65° and they were doing pretty well.

elodea (Elodea dont know specie name... ) also will do pretty well.

Puma elodea is egeria densa.

Vallisneria americana will take low temps, but is likely to be too big for the tank.

Ditto spadderdocks, cool water plants, but huge.

Willow moss is cool water also, but not in much local distribution in the US.

Sagittaria subulata does well cool, and is much smaller than Val.

Pennywort, already mentioned, is good.

Dwarf hairgrass likes it cool also.

Hornwort prefers cooler water.

Lots of choices, but size is likely to be the most limiting factor in a small tank.

I meant common pond elodea which is a seperate specie, even seperate genus,

Elodea canadensis


Some more plants

Lagarosiphon major (formerly Elodea crispa)---- African water weed
Java ferns
Java moss
Maybe banana plant

I'm trying to think of a plant that will NOT grow at these temps and I do not know one.

Crypts might be mentioned but this is DOGMA because I've grown crypts at lower temps than you mention.

All my tanks are unheated except for the marine tank.
Gnerally it's better to have lower temps than higher for plants.

Oh wow. I had no idea there would be so many. I can get at least half of those at my LFS. Thanks alot you guys, and yeah, size is a concern, but I'll work that one out myself.

How then do I deal with moving plants from a warmer aquarium into a cooler one? My panted aquarium is at 24 C but the unheated sits at around 18 C lately, and the stores around here keep their plants in warmer water too.

Thanks

Almost the same as you would a fish. Put the plant in a cup or ziplock bag and fill the bag up with water from the warm aquarium. Then, let it float in the other tank until the temperatures equalize. HTH
