Dwarf or not?

[Erised]

So a couple of days ago I finally went and bought my dwarf puffers ... lovely shop but the people that work there, ugh! However, thats a completely different story

However, we noticed that out of the 3 dwarf puffers we bought, 1 just doesnt look like the other 2 at all! I've heard that puffers can change their colour and markings cause of stress, so at start I didnt pay too much attention to it. Now however, we're a couple of days later and it still doesnt look like the other 2 at all! I'm now starting to wonder if it is even a dwarf at all (I'm 80% sure it is, but dont really dare to say it out loud yet). I'll post some pictures for you to compare it ... and if the markings/colour are indeed changed because of stress, what can be causing this?

I see what you mean. He's very slim and has no spots at all. Looks like a tiny juvenile t. modestus but only time will tell I guess.

It could just be a colour mutation.

Feed them well and see what happens!

Thanks SirMinion =) ... Glad I'm not the only one who isnt sure at all though! Thought I was just being paranoid He is a bit bigger than my other 2 dwarfs, and quite a lot more aggresive as well. I guess we'll see what he ends up like =)

Umm, I just did a search for t. modestus and dont seem to have any luck finding anything. It keeps coming up with c. modestus all the time however, and 1 website telling me t. modestus was the same puffer but it not being the full name ... so I'm guessing those 2 are the same puffer?

 

[SirMinion]

Yes same fish. If I remember rightly, one name is carinotetrodon modestus but it's also known as tetradon modestus and aurioglobus modestus

I might be entirely wrong as I was just going by the shape & colour and many puffers change both of these as they mature.

Like I said, we'll just have to wait and see!

watch that aggression though, make sure it doesn't get out of hand.

 

[Erised]

I will =) ... got an empty tank coming up soon, so if it gets out of hand he can always go on his own

 

[appleblossom]

aww he looks so thin

i diagnose bloodworm! and lots of it!

best of luck with your puffers! they are the best fish in the whole world

Yay! Go puffers! Again good luck with puffers and be careful not to overfeed!

Hard to tell from the angle, but IMO it looks like a juvenile Tetraodon cutcutia (the flared nostrils and longer snout look the same), definately not good for a mixed puffer tank, get to about 4 inches and are very aggressive.

edit: Shape doesn't look right for Auriglobus modestus (also known as Chonerhinos modestus), the head looks too wide.

 

[SirMinion]

Shape doesn't look right for Auriglobus modestus ...the head looks too wide.

I thought that too, but as it's such a baby, I though that it just had a big head like babies often do.

You're right about the snout though, it's too long for a modest, but right for a cutcutia.
However, we have a juvenile cutcutia and the body shape is a lot rounder than that, but of course we've had him a while and he's well fed.
Ours also has quite prominant spots which that one does not, but as you are aware, puffers colours can change at the blink of an eye.

I really don't know. Could be anything

Maybe he's a crossbreed?

 

[Puffer_freak]

Unlikely, its hard enough to breed a normal puffer, let alone cross breed it.
