Thanks for reply FL
I've seen them max size before, and with that lightning fast speed, they'll truely need a titanic tank.

Problem is I've never seen them attack each other, everything I've read is against what I saw.
They're very common in my country by the way

Anyone knows or have experiences about this fish?
I've read that they attack each other when young and cruise in pack as they gets older.

Problem is this is absolute against what I saw in the wild! They swim in shoal, really big shoal when they're tiny.
The bigger they get, the smaller the shoal

Yep, it was really cool!
I will have another 2 trips to 2 other areas, I'll try to bring a camera with me and keep it safe in a plastic box

Thanks
I'm really surprised that GBRs could have such a long fin! And I'm so lucky to have him

Just want to share my german blue ram with a magnificent fin!!!

You've done something really great! I bet the fish love their new home!

You'll never understand the fun of keeping fish unless you actually keep them in the right way and watch them living healthy and happy.

I don't know about your fish but my gold fish could be hand-fed. You should try sometimes!

I've read that but there's no info how fast should the salinity change so I'm really running blind

I didn't bring a camera with me as I don't have a decent one and it's too risky as there was some muddy area that will sink really fast, I didn't want to break the camera so I left it at home

I just got home from a saltwater marsh today and it was awesome!

I've collect a fine amount of mangrove propagule, some even started to root! I'll buy marine salt and plant them in salt water tomorrow!

By the way if anyone knows or have experience with mangrove please give me some advises. Do they have to be kept in water with the same SG? The area I collected them was 1.25 SG.

Didn't see any puffer, maybe the area was too salty?
Found a purple-claw crab which was living in drift woods submerge completely in water... very interesting and attractive crab.

It was all good but some kind of mosquito-like insect stung me all over the place... they don't have lethal poison but their poison makes you super super itch and swell really big. I don't know what are they but insect repellent doesn't work! They have white wings and very small, you can easily mistook them with sand on your skin.

That must means your fish is very healthy!

The angel was the boss simply because he's bigger.

Molly and platy has been fine because they're hardy. And so neon and betta.... but angels are not, that's why they die so fast in an unsuitable tank.

Still you should pick soft or hard water fish when you get your 180l.
Pet shops usually give poor advice and care more about profit to be honest
