The eggs survived storm Katie and I’ve had great fun over the last few weeks. Several female tompot blennies have been to visit to lay their eggs in my home crevice as they know I’m a good dad. I was the first of the 4 local males to be looking after eggs and it’s a sure sign that, as soon as one female has laid, others will follow quickly after. They seem to prefer to lay their eggs with a male who already has eggs; going for proven quality and safety in numbers! There’s a small male in the crevice near mine and a generous female eventually laid a few eggs with him, while she laid a lot more with me.
I’ve now got eggs on the floor and ceiling and have a lot of egg guarding to do! I was busy at the back of my crevice the other day and a sneaky Connemara clingfish dashed in and ate a few eggs that were near the front entrance to my home. As soon as I spotted the cheeky intruder, I darted over and gave him a quick nip to scare him off. Hopefully it was enough for him think twice before coming to eat my babies again! I have to be careful when I choose my crevice home as these egg thieving clingfish are able to squeeze into narrower gaps between rocks than I can. That means they can hide in parts of my home that give them easy access to my eggs but which I can’t get into to chase them out. Now that is frustrating!
It’s hard work being a tompot blenny dad because lots of the reef dwellers are after my precious eggs. First the Connemara clingfish and now a topknot, a flatfish that likes to live on the rock, keeps trying to come in to my crevice. He’s quite big so I have to charge at him and nip at the same time so that he takes notice and goes away.
It’s a good thing I got my crevice home clean and ready for my female visitors. Just before Easter, a female that we now call Betty came to visit me and she laid a beautiful raft of eggs for me to look after. You can see me in the background of these photographs. The female tompot blennies tend to be paler than the darker more reddish coloured breeding males. In the bottom photograph, Betty is in the middle of laying her eggs and her ovipositor (egg laying organ) is showing.
Teresa and Paul came diving to visit us and were pleased to see that we had started to breed. Storm Katie came through a couple of days later so they are not sure whether Betty’s eggs have survived the storm. In any case, I’ll be trying to attract several other female tompots to visit me over the next two months to lay their eggs. Hopefully the weather will improve, so it will be easier for me to be ready for them!
When I have eggs to look after, I wipe them over with my special glands (that look like miniature cauliflowers) to keep them clean, healthy and free of bugs.
As soon as the sea is calm enough, Teresa and Paul will come and see me again and will be able to let you know how we are all doing.
A while after I watched those youngsters fighting, I had an argument of my own to sort out. Another large male tompot blenny (that’s him on the right in the video) was spending too much time near my home, so I swam out to confront him. Our stand-off lasted nearly 30 minutes and the video below shows just a small part of it.
You can see we were both trying to scare each other away and prove we were the bravest, without actually using our teeth and risking getting a nasty injury. We’re a bit older and wiser than those youngsters! You could say we were ‘all show and no go’ but a lot of adult animals use that tactic, not just fish like me. Anyway, you’ll be pleased to know I saw the intruder off in the end and am still the proud boss of my crevice!
Over the summer the eggs that I have been caring for have developed well; you can see them on the ceiling above my head. They look like amethyst gems (see Barbara’s eggs in the photograph) when first laid, then progress to a gold colour with a paler centre. Just before they hatch, their eyes become very obvious and it looks as though they are watching what I’m up to. I still clean all of them regularly by wiping them with my special gland (see blog 26/06/15) and protect them from predators.
It won’t be long now before the ones with well-developed eyes hatch. I will be sad to see them leave but my job is done. They need to go into the plankton and find the right size food so they can grow into young fish.
I’m very excited to be starting my blog on WordPress, telling you all about the wonderful world in the sea around Britain. Who am I? I’m a small fish, a tompot blenny, that lives very close to rocky and stony beaches. You could spot me if you go snorkelling or you might sometimes find me in rockpools if the tide is very low.
In my blog, I’ll be telling you all about me and what my superb red head tentacles are for, what happens in my life and what all my neighbours are doing. I usually live in the same spot for a long time, and I will tell you about the other animals that I see from my home – like crabs, starfish, cuttlefish and many more!
