I just noticed there's 3 Banggais holding at this moment .
In a way I regret getting the original couple a few years ago and the reason is precisely this: they breed and release a small group of baby pandas in the tank, and they're the cutest baby fish ever... and it's tough.
Other than that they're fascinating fish. The dynamics of the group is really complex.
The reason there's 3 males holding at this moment is because the mother of them all got her male pregnant, kicked him out and he had the babies on his own.
In the meantime she seduced one of her sons (a widow, whose wife she killed, I believe), got him pregnant, than she took her original husband back and got him pregnant.
Just by coincidence, one of the young males is also pregnant from his sister.
Yesterday I decided to do some prunning and nearly destroyed the left side of the main valley.
The teal slimer and the forest fire detached from the rock and fell and the only way to put them back close to their original positions was to lean them against other corals. This will create lots of dead areas.
I wanted to prune the areas with less light, so I tried to cut lower branches. The idea is also to create more passages for the fish.
One of the components that I think the hobby misses is sound and I decided to install an audio system under the tank.
I created a sound file with 24 hours of a mix of reef sounds and it's in synch with the programming of the pumps . The pumps simulate 2 high tides during the day.
The sound file begins at 10 PM and it begins with calm reef sounds, mostly clicks from shrimp.
In the morning, as the pumps increase speed, the sounds of a more active reef increase.
When the pumps get to 120% (they're overclocked), the sound of the waves is really loud.
I have one of the speakers right beneath the bottom glass and the other facing the front of the tank. The subwoofer is at the bottom of the cabinet.
The funny thing is the synchronicity of the pumps and sound is really noticeable, not just because of the movement of some corals, but also the sound of the surface agitation, because the 2 pumps are attached to the eurobrace.
I don't know if the fish can hear it and if they do, if they like it. I do.
The Tomini tang hates the diamond goby and always chases him back to his burrow beneath the magnifica pillar whenever he sees him out.
The goby is so scared of the Tomini that seeing him 2 feet away is enough to make him rush back to his burrow.
Yesterday in the evening, the goby decided to move to the front centre of the tank and began digging. When the Tomini saw him, he immediately attacked him but the goby fought back!
It's interesting how the motivation of getting a new home gave him courage.
That area of the tank hadn't seen any sand movement in a long time and the excavations caused the water to fill with sediment. I guess the corals are enjoying it.
The heraldi angels usually spawn everyday just a few minutes before lights turn off, but in the last few days, the female wasn't interested. It used to be the opposite. The male danced and darted around trying to persuade her, but to no avail.
He was definitely not happy and occasionally even chased other fish, including the comets.
I was getting worried that there was something wrong with the female but yesterday they spawned and bit earlier than usual. The male even wanted to have another go.
It's the first time I keep comets and I find it difficult to understand their behavior.
When I got the 2, I though they were the same species and I was hoping they would pair up. I now know that they're an argus and an altivelis and I'm now 99% sure it will never happen.
The argus is a much calmer animal and although he's smaller than the altivelis, he still has the upper hand.
I'm always scared when a smaller fish has the upper hand because the moment that the relationship is reversed can have fatal consequences.
They have different body language.
The altivelis does the defensive flapping of the tail while swimming backwards when I move too close to the tank and sometimes when he is startled by the argus. I've never seen the argus do that.
The argus moves his ventral fins almost like a shrimp moves his antennas. I've never seen the altivelis do that.
The argus is an absurdly elegant fish.
This is the argus just before I got him:
I looks like it hasn't grown at all in 28 months.
The altivelis was a young fish, probably 6 months old from captive breeding and it trippled in size.
The argus has always been much more challenging to feed. I recently got dried krill. The first time I showed it to him outside the tank he went nuts. He hasn't seen a shrimp since he was caught in the ocean.
