View Full Version : What Kind Of Fish Is This ?
Hi all,
I collected a strange fish from Menai Straight (Irish Sea) a few months ago, but I don't know what kind of fish it is.
The size is around 3".
I tried to feed it, but I never saw it feeding.
After a month, the fish died of hungry (I guess).
Before it died, it had got some greeny colour.
Do you know whether this greeny colour is a disease or nothing ?
Have a look at the photos

I had another strange animal. It looks like a sea slug, but I'm not sure.
The size is also around 3".

If anyone know these species, could you tell me please ?
Thanks.

Water : 6 weeks (mainly sea water of Irish Sea and sometimes changing water with cheap sea salt)
Filter : power internal filter (PENN-PLAX CASCADE 600) and undergravel filter (no function due to lack of air pump being used for skimmer)
Water current : current from the internal filter (200 l/h)
Skimmer : DIY airstone driven skimmer made of water bottle.
Temperature : 25 - 26 C
Salinity : 1.022 - 1.023
pH : 8.2
Gravel : coral sand 5 cm
Live rock : 5 kg (collected from the sea and attached some algaes, shells.)
Rock : 2 kg (bought to provide some shelter for animals)
Lighting : 2 low energy bulbs (9 W, 16 W)
Animals : 2 percula clown fishes, 30 local prawns, 3 local crabs, 4 local small mussels, 20 local snails, 3 local anemones (two dead after a couple of months and one left)
Food : frozen prawns or frozen artemia, sometimes a little piece of fish
A Gurnard possibly and a sea apple?
WOW WOW WOW please stop.
When I first saw your set-up I thought you had done a North Atlantic/Irish Sea Biotope. I looked at this with much interest. Then I see your temp is 25C-26C and you have 2 clownfish. The temp of the Irish Sea this time of year is about 5C and not a clown fish in sight. What Im saying is that you cant keep a Cold Ocean Biotope and a Reef Biotope together
the fish is possably enophrys bubalis which is one of the sea scorpions. it eats mainly invertabrates and small fishes. i have to say that johnnyboy is right you you should not keep tropical marines with cold water marines together.
Round here (Scotland) your fish is what we call a Sea Sculpin. I don't think you starved it to death as these guys will IME eat just about anything that doesn't move fast enough. I reckon it got cooked :(
As posts above: Your tank is far too hot for livestock from our waters. Some rockpool creatures would be able to stand it for a while but their lifespan would be greatly shortened.

Thank you for your reply.
It is an enophrys bubalis and a sea apple. I've found out a photo of these species.
You are right. I shoudn't mix marine and cold marine animals in a fish tank.
Initially, I started my fish tank with cold water animals.
After sometime, I wanted to put two clown fishes.
I slowly increased the temp from 20 to 24 C.
I also reduced the gravity from 1.028 to 1.023.
Apparently, it wasn't too bad for the cold water animals.
My local prawns, crabs and gobies are ok.
Because the gobies attacked the clown fishes, I got rid of them.
Hermit crabs are dead. I think it's because we heat up the house too much and the fish tank temperature went up 27 C. I think hermit crabs should have suffered hot.
Enophrys bubalis is mainly dead of starving. When it died, it was really thin and the belly was almost attached to the back. I tried to feed it with different foods but I never saw it eating something for a month.
Sea apple is dead 10 days after. But I'm not sure whether it died because of being blocked between a heater and a tube or the too hot water.
My prawns seem to be happy. Sometimes they get pregnant with plenty of eggs. But when the eggs become babies, the clown fishes are happy to eat all of them. So I always fail to breed them.
My mussels are ok. They have been living 3 months. I also tried to keep sea shells and cokles. But they are all dead 3 days after. I think they suffered the different temperature and gravity. They also suffered by the prawns which attacked them a lot.
Now, I don't put any more cold water animals in my fish tank.
Hopefully, my fish tank will go very fine.

i think the nudibranch is a sea lemon not a sea apple
You are right.
It is a sea lemon rather than sea apple.
Thank you, Colin.

is it legal to collect from the wild in this manner?
it is legal to collect certain animals from beaches, but you can get fined if you take protected animals from a sssi beach.
Is this a wind up?! :unsure: :o :huh:

any ideas where these beaches are, and what species are included? is there a website? - I would have thought Menai would be protected.....
3 local anemones (two dead after a couple of months and one left)
Hermit crabs are dead.
Enophrys bubalis is mainly dead of starving.
Sea apple is dead 10 days after.
:angry: :angry: :angry:
Either tell me this is a wind up or you have no idea what you are doing and should stop adding any more to your tank until you have decided what type of livestock you are going to keep marine, tropical, cold water salt or fresh.
this is the most annoying thread I have ever seen :angry: :angry:
I would agree, however please dont make this personnal.
He says he now knows not to add cold water livestock to a tank running at 25c so lets hope he has learnt a valuable lesson.

why is it floating?

help I'm in real trouble
was walking down the beach and found a baby seal, nice little chap so i popped him in a bag and took him home
he loves the tank but has eaten all my fish!!!!!!
wife is now really p*ssed off with me cos he keeps splashing water on the new carpet.
help!!!!
Alright, there's no need to take the ****!
Min, when I first read your very first post, I just thought you were having a bit of fun, so never replied, but it now appears that you are serious.
I would advise you to read up a lot on the hobby before you go any further, as you will keep having these deaths if you carry on without sufficient knowledge. There are lots of people on this forum that will be happy to help you.
It is not good to use local sea water for tropical marine fish, and you are lucky your clownfish have survived this far. Whilst Menai is a beauty spot on LAND, the sea is very polluted, even if you went out a mile or two (which I suspect you haven't done). The sea water where these delicate fish come from is much less polluted, and less prone to carrying diseases, which they would not be able to fight. You say you make up the rest of the water with "cheap sea salt". I am beginning to think this may not even be marine grade seasalt, but cooking salt. Am I correct? If so it is totally unsuitable, and you need to buy it from your local aquarium shop.
Your decor etc. looks like a tropical tank, not marine. That's ok, but I am concerned about your substrate being wrong, and also your greenery carrying disease too.
To keep tropical marine fish, as your clowns are, needs at least some basic knowledge.
If I were you, I would lower your tank temp. and carry on keeping local fish, and have an Irish Sea tank, until you gain more experience. Then read up, and ask as many questions as you can about lighting, feeding, filtration, specific gravity, water testing etc.
You could then progress to tropical marines happy in the knowledge that you will be able to keep your stock alive. No point if everything that you put in there dies is there?
Good luck with it, and ask as many questions as you can!
( If this is a wind-up, I won't be a happy Easter bunny!!)
:o :o
if this is serious then i would be having words with the lfs that sold you the clowns.
not having a go, because i'm sure you wouldn't have done this deliberately if you knew the consequences, but why did you think it would be ok???
I'm just sorry that animals had to die for him to figure out the basics. Buy a book :(
wife is now really p*ssed off with me cos he keeps splashing water on the new carpet.
He he he Classic.
Think it's time to close now.
