no heater

[Thalassa]

I have some coldwater tanks in my house gets as low as 60.
Currently have:
badis badis
black tiger dario
common goldfish
paradise fish

any other suggestions?
cold water cichlids?

Thanks

 

[Ansorgii]

Jordanella floridae
Elassoma gilberti
Elassoma okefenokee
Etheostoma spectabile
Yaoshania pachychilus
Aphanius meandricus
Enneacanthus chaetodon
Fundulus zebrinus
Notropis lutipinnis

Are all relatively small, colourful and might need even colder temps during the winter to flourish/breed.

Some subtropical channa can also take that.

Any of the Uruguayan, and argentinian cichlids are good in no heater tanks.
Uruguay is much like the state of Georgia in climate so these cichlids are perfect.

Australoheros left...................................Cichlasoma dimerus Bella Union middle................................Gymnogeophagus "rio Yerbalito right

Crenicichla saxatillis (Uruguayan variant left above) Gymnogeophagus sp Paso pache right (above)

I have had temps drop into the 50sF for these. above right, a winter shot taken in Argentina, yes that is snow..

In addition to all the previously mentioned fish, some great coolwater cats would include Corydoras paleatus and Scleromystax barbatus, which both do great in the 55-65 range in winter. In terms of plecos, I have a couple of Hypostomus laplatae thriving in that temp range now, but have only had for less than a year so can't speak to the long term. Hypostomus luteus has a range that implies it would do well at those temps, but I don't want to experiment with a $400-$500 fish until I see somebody else try first.

I have some Garra rufa (Doctorfish) and Garra flavatra (Panda Garra) doing great at 55-60F with my goldfish.

Others that I have kept down to 60F during winter with excellent success...always with warmer temps during the summer...include Rosy and Odessa Barbs, assorted Goodeid livebearers, Buenos Aires Tetras, plain ol' Xiphophorus hellerii swordtails, Heterandria mosquitofish and Medakas (Oryzias latipes).

cool! are those pike cichlids at the bottom?

 

[duanes]

They are Uruguayan pike cichlids collected by Ken Davis in Uruguay (Crenicichla saxatillis).
For your tank, the more northern South American pike varieties would probably not work.

Mine hit about 10".

I believe Ken Davis (a member here) is initiating a collecting trip to Uruguay in the near future.
Below is a link to one of his previous collecting trips

Awesome fish. They eat everything else in the tank with them; half of them choke to death trying to eat stuff that is too big. Then they turn upon one another and continue eating that way until there are three left. Then they pile up on one another into a "nesting dolls" kind of puzzle, with dead fish stuck in mouths...within other mouths...and everybody dies!

I don't know how they spawn successfully.

Very cool fish, but I gave up trying to keep more than one.
