They'll spawn in a bit of java moss or bushy plant like ambulia quite happily. Best trick I've found to get them to initially spawn was after conditioning them with lots of beef heart so they're big and fat, is to let the water evaporate from the tank, and then when there's a swing in barometric pressure (there's a storm or something) fill the tank right up with no salts added.
There should be lots of people who have done it, and I'm sure they all have their own methods :p

The guppy-like fish you have is more than likely a "mosquito fish". They are probably our number one pest here in Victoria, if not all of Australia (yes, even more so than Carp).
Any time you're serious about breeding fish you should keep then separated, unless their breeding requirements stipulate otherwise (eg. Synodontis multipunctatus), otherwise it's Darwinism at it's finest my friend ;)

Ive heard so much about these mosquito fish but what do they actually do and how big do they get?

[Woodsy]

They are livebearers like your classic American fish (Platies, Guppys ect.) but are adaptable to an amazing variety of water conditions. Originally relased to control mosquito populations (hence the name) they have bred out of control in our waters, and out-compete our natives for food and habitat.
They can grow to a couple of inches and will breed in almost any type of water.

i tested the ph of there water when i first got em and it was near 8
then i added a bit of ph down whitch got it to about 6.2
then a added abit of ph down again by mistake instead of ph up and it went down to like 5 and there fine

it was hard to judge the amount because its a 1.5 gallon

the tank also has no heater so ranges from about 30 to 18 degres

i also caught my big brother while drunk pour beer in there whitch cant be good for them but it was just a BI


so these have to be the tougthest fish ever they have survives a 3 ph change in acidity about a 12 degree change and beer
oh and mum took the filter out at the plug to iron adn fogot to put it bak in for 3 days so there blody tuff

winter breeding fish. simulate the winter 20-30% water changes or more. drop the gh to 6-5 drop's, kh to 3 drop's
keep in mind doing this is and may be deadly, so monitor the water regularly.

The mosquito fish mentioned here? Do they make good feeders for any other fish or yabbies/snails?
