Over the years I have bred lots of different species, some for fun and some to see if I could do it.
Beside the Betta splendens this year I am spawning, Neons tetra, long finned gold and silver Danios, fancy guppies, gambusia.
Today my long finned albino plecos Ancistrus sp fry came out of the cave, looks to be about 30 or so.
Last year I spawned the Corydoras aeneus or the common bronze cory cat beside the ones listed above.
Breeding and spawning is lots of fun in my opinion and you can learn so much.
