Fish fry in Riccia

I have masses of Riccia in my tank so decided to thin it out. Rather than throw it away I put it in my spare tank which is currently fishless. Looked in this morning and saw at least three small fry - growing them on to see what they are. I expect they'll be either neon rainbows or emperor tetras both of which spawn very frequently in my main tank.

In future I'll put any plant trimmings and Riccia in a tank for a few days to check if there may be fish in there.

nice one, they're most probably rainbows ;)

the tank they're in does have a cycled filter and heater, right?

Emporor tetra fry need a very low PH as they're black water fish and as such need lots of water changes, rainbows are the exact opposite and respond badly to water changes why fry.

I keep this small tank ticking over all the time as a quarantine tank - I have never put new fish straight into my main tank. This has helped me to avoid disease outbreaks for many years.

Since I've had heavily planted tanks quite a few fish fry have survived in my main tank, some less welcome than others! So far I've had many Ancistrus - never saw them spawn, the 1cm long babies just appeared, Emperor tetras, Lemon tetras, cherry and chequer barbs (all welcome) and dozens of blue platies (less welcome). I bought three blue platies about five or six years ago. They have produced several generations of what must be very inbred offspring. Luckily my LFS will take them although I have taken them out of the main tank into a spare 60cm.
