Benny the Blenny’s babies (juvenile fish) 2cm long are settling back on the reef

You’ve seen how my amazing my babies were swimming around in the plankton. The ones that managed to avoid being eaten and found enough plankton to eat have grown to around 2 cm long and have now settled back on the reef.  The researchers are not sure how they find a good home reef. It may just be luck or something to do with them being able to recognise the smell of the area they hatched from. Some coral reef fish know which reef is home from the sound the waves make!

When my babies first settle they are quite colourless, but soon take on camouflage colours to help them match their surroundings. You can see that their head tentacles have started growing and their pectoral fins are just visible with some black pigment.

Thank you to the National Marine Aquarium Plymouth for their help in getting this photo. The NMA is an excellent place to see tompot blennies like Benny the Blenny and lots of other UK marine life.
