Jakarta Aquarium

In an quite interesting discovery, Renzo the South American fur seal most likely came from the Underwater World Langkawi in Malaysia. An article posted in 2020 and an Facebook post by the aquarium themself in 2022 referred to one of the SM fur seal as "Renzo". Though, there's apparently had yet been any posts or statements from the Underwater World Langkawi about the departure of one of their seal (I have no clue if the seals there are particularly popular and heavily-marketed, like Holly was in Jakarta Aquarium), but this is rather unlikely to be a coincidence.

From a visit on 06/02/2025, an wobbegong was spotted in the ray/seashore tank in Jakarta Aquarium, most likely the same fish that was displayed in a different tank a couple of years ago.

It's hard to specify which species this is from low-quality picture like this alone.

Glad to see it returning! I assume it's also Leptolineatus, same species as JAQS' wobbegong

Would it be possible to start some form of breeding program for the species in Indonesia?

There's breeding projects for bamboo sharks in Jakarta Aquarium and BXSea, but that's mostly just that. I don't recall if there's any particular shark breeding program and conservation in general. Especillay considering a lot of sharks, including all the wobbegongs in Indonesian aquaria, are derived from catching by fishermen or even some commercial suppliers, which then displayed at those aquariums for likely the rest of their life without even a proper research into more crucial stuffs like breedings or such.

Indonesian aquarias, aside from sea turtles and reefs, doesn't really do much conservation from observations aside from informations on sea pollutant and enviromental damage that guests most often than not just ignore. A lot of shark conservation in Indonesia are done by NGOs, like with ReShark releasing zebra sharks to the Raja Ampat islands a year ago (Whats funny is that these sharks are breedings from SEA LIFE Sydney, further showing the priorities between Indonesian, including the majority of SEAn aquarias, and anywhere else).
 
So I'm in Jakarta Aquarium rn, since I haven't visited this place for a year because BXSea kinda stole my heart and I don't wanna forget this place because it's the first mall aquarium in Indonesia so, without further ado time to report some changes:
  • At long last! The sturgeon tank is no longer overstocked! Its cyprinid inhabitants (mahseer and hampala barbs) has been moved to the serval exhibit where it inhabits the moat alongside red devil cichlids.
  • The emperor newts are still there, but its exhibit lacks water.
  • The wobbegong is still there in the ray tank. It's pretty shy and passive, hiding behind a rock. There are no longer Kuhl's maskrays in the shallower ray tank.
  • There are only 2 meerkats left in its exhbit, and only one binturong left (Jimmy).
  • The sea dragons has perished (or phased out) and in its place is a mix of temperate fishes such as snipefish, pineconefish and old wives.
  • The ribbon eels are nowhere to be seen in the cowfish tank. Either they're hiding or phased out.
  • The gurnards has either perished or phased out, leaving only peacock flounders in its exhbit.
  • The payaras from the dangerous freshwater fish exhibit has moved to the sturgeon tank. The goliath tigerfish is still there, along with the spotted gars and small Xingu river rays.
  • There's only one silver arowana left in the waterfall basin tank, and only three Jullien's golden carps left as well.
  • All of the jellyfish tanks are filled with mangrove jellyfish, and the upside down jellyfish are still there.
  • There's only two popeye catalufas left, along with a few flashlight fishes. The adjacent tank is empty.
  • Renzo is still doing well thankfully, and it was very fun watching its show and interacting with it.
  • There are sea turtles in the main tank, one green and one hawksbill.
There are more animal losses than additions this time, hopefully they'll improve in the future although BXSea is much better than JAQS in my opinion.

The emperor newts

Again, the newts at JAQ are the crocodile newt (Tylototriton verrucosus), which have a more muted orange coloration as well as being more widespread in the local trade (Where JAQ get the majority of their non-saltwater collection from).

Which cowfish tank? I don't think I recall seeing a cowfish tank in JAQ last February. The long, wall tank across the garden eels (Where the lobsters and cowfish once were) now became an algae/seaweed and sponge tank, as well as some fishes.

The ribbon eels are in one of cylindrical tank, next to the pufferfish.

It turns out, this species are quite rare in the trade, more so in Indonesia. A lot of "black diamond" rays are potamotrygon leopoldi. The difference in patterns between individuals are just a result of selective breedings and captive farming.

The cowfish tank is the cylinder tank with a tower in it near the Outer Reef exhibit (one of the two smaller cylinder tanks). It has the signage for the ribbon eels but none were seen there.

The cowfish are new in that tank then, the ribbon eels has been there earlier. I recall this tank also having a couple of triggerfish species (Rhinecanthus verrucosus and rhinecanthus aculeatus) in February, I assume they were gone now as well, no?

Didn't see any triggerfish except the ones in the outer reef tank

That's great! I wish those meerkats got phased-out ASAP and got replaced with central bearded dragons

Sad to hear the sea dragons got phased out, Glad I'm still lucky to see them during my last visit in January.

The payaras and the goliath tigerfish should've been phased-out, while the florida gars and the river rays got moved into the waterfall basin tank. For the dangerous fish tank, I'm still hoping the tank got converted back into an aquascape tank.

That single silver arowana and three julien's golden carp should be phased out from waterfall basin tank in my opinion cause it may outgrow in that tank, other fishes in that tank such as aligator gars, catfishes, etc should be phased out from the tank cuz they may outgrow and would cause the tank to crash and got replaced by a medium-sized fishes.

It would be a great idea for JAQS to start sending their larger fishes to TSI's pirarucu tank
 
During a visit to Jakarta Aquarium on Thursday last week (10 July, 2025), there's few updates:
  • No dart frogs appears to be present or atleast visible, the terrarium design shifted again.
  • An anabas testudineus has been added in the tank for blind cave fish and elephantnose fish.
  • Several mullets (Mugilidae) are present in the seashore tank.
  • The previously pufferfish and scorpionfish tank has been revamped to house assorted coral reef fish again, including the Valentin's sharpnose puffer.
  • The obtuse barracuda are unfortunately no longer on-display.
 
Jakarta Aquarium recently added african spurred tortoises (centrochelys sulcata) to the capybara exhibit.

What a weird mix of African tortoise and South American large rodent. Could've added red-footed tortoises instead.

Moreover a desert tortoise. I bet they don't even have Ultraviolet lights installed there.

I would have voted for semi-aquatic turtles like Orlitia or even Arrau turtles if they can source them, but I surmise they used Sulcatas mostly because they're interactable and it isn't hard to find people willing to surrender larger specimens.

"Don't worry be Cappy", what a joke

Pingoo has closed down and apparently it's going to be replaced by a pizzeria. However, I asked the clerk at Ocean Wonders and he said that once it opens, the penguins can be seen again as usual. For now, they can only be seen during show times (12 PM and 4 PM) until the pizzeria opens.

Weird because rn BXSea and SWA are getting Ws (one is getting African penguins and the other one is getting Halmahera epaulette sharks) while this one has been a bit sloppy (adding Sulcata tortoises in the capybara exhibit + Pingoo's closure) so this is an L for JAQS

Well TBH Pingoo's food is kinda overpriced and I never ate there since the day they opened back in 2017 :(

Too bad it closed, I had plans to eat there and try their fish & chips for my next visit to JAQ. I wish they used pingoo’s area for JAQ’s extension. I really wish JAQ made a tank for japanese spider crabs.
