They may as long as the surrounding air is warm enough and the water chemistry is to their liking.
No. Gouramis will be very aggressive to the tetra.
If you are considering freshwater fish, you can try honey gouramis. Another good choice for breeding is various angels because they should sell well.
Gouramis aren't really great fish to have together unless they have room to move around (e.g. at least 5 gallons per fish). Your tank is MUCH too small to have two gouramis, they're fighting for territory. If you don't want to return one to the fish store, then you should definitly just get a bigger tank. Unless you have dwarf gouramis, you should have them in at least 20 gallons. It also depends on what kind of gouramis you have. Some are more social and are more likely to school (dwarf gouramis, pearl gouramis) whereas others prefer to be top dog (opaline gouramis, blue gouramis). Good luck!
No, gouramis are egglayers.
no .................
yes.
no. fish can only mate with fish of the same species. Gouramis mate with gouramis and platys mate with platys.
adjust the heater on your tank, it will take a while to change the water temp, so as long as it is gradual, it wont hurt em
Kissing gouramis (Helostoma temminicki) are Anabantids and build a bubble nest in which to guard and rear their ova (eggs). It is not likely that they will breed for you until they are adult and over 10 inches long
Gouramis come in a large number of colors. You can not determine their sex based on their color.
You cannot breed Legendary Pokemon without cheats, except for Manaphy with Ditto.
I have a blue gourami with my gold
