6 ideal fish to spend the summer outside
I’ve chosen the fish below because you will probably get a long outdoor season with them.
If in doubt, place a heater in the water and set it to come on when temperatures hit 20°C.
Paradise fish, Macropodus opercularis Variatus platies, Xiphophorus variatus Eartheating cichlids Gymnogeophagus spp. Hillstream loach, Gastromyzon spp. or Pseudogastromyzon spp. Great for streams, waterfalls and rills; need high oxygen. Moustached danio, Danio dangila. Net these to avoid jumpers. Hoplo catfish, Megalechis thoracata.
