They are not big tanks, so you need to take that into account. I think they would be too small for angels and kribs, possibly even for rams, though I could be wrong there. Also, are these your only tanks, that you could use as temporary spawning tanks, or would the parents then have to live there full time? You can get away with bigger fish if they can then be removed. And most important, what is your water like- or would you able to use RO water to soften it if it is hard?
Have you had any previous breeding experience (guppies or similar?). How much trouble would you be prepared to go to to find them suitable food?
The easiest to breed are probably the livebearers- but there are other problems involved here, as it may be difficult to find homes for yet another generation of guppies or platies. Also, once they get pregnant, they keep on and on giving birth. You could try a more unusual livebearer, something like heterandria formosa or limias.
If you want to go for egglayers, there is a difference between eggscatterers like danios, barbs etc and fish that practise parental care.
The easiest eggscatterers are probably danios, corydoras and cherry barbs. All of these could be spawned in your larger tank, though it is too short for a permanent home for the danios, arguably even a bit short for their spawning runs. I would go with either corydoras or cherry barbs.
For corydoras, the best ratio is 2 males per female- you might be able to fit 2 trios in there for spawning. Condition them on livefoods for a few days and then do a water change with cold water, should get them in the mood. They may want plants to spawn on, though many are happy to use the glass. Eggs then would have to be moved into the smaller tank before the parents eat them.
Cherry barbs you want the opposite ratio: 1 male+ 2 females, or a male/female pair. Condition on livefoods and provide plenty of cover/spawning mops.
You can be confident that most tetras and rasboras will never breed in your tanks unless you can provide soft acid water; also, many tetra eggs are lightsensitive, so will only develop if you keep them in a specially darkened tank.
As for parentally inclined fish, the most common breeders are probably bristlenoses and cichlids. Bristlenoses are too big for your tank, but there are some possible cichlids. If you can provide hard, alkaline water, shelldwellers might be your answer. You could fit a breeding pair of multifasciatus into your bigger tank. Not sure about the rams- ask in the New World cichlids forum. Rams would want soft acid water to breed. Bolivian rams are possibly another option.

.My dad said when we move house i can have the little garage at the bottom of the garden for fish.I might start breeding bettas then.What cichlids are good?i have a pair of wild rams in my community tank.But the word wild comes to mind lol.My mates doing kirbs so i dont nt to do them.What about convicts or would they breed to often for my tank space?Any thoughts would be helpful cheers.
