About Me

My name is Sebastian Grant, I keep and have worked with a huge diversity of species, and yes I know how lucky I am! Here in my short video's and writings I will try to convey how I've kept some of the animals I have kept mainly at home but also at work over the years. I will try and be honest about what I've done. On how I’ve kept things both at home at professionally and what’s gone wrong. It has long been a belief of mine that many captive animals survive in spite of what we do, rather than because of it. Here's how and why I've messed up or succeeded. The videos are mainly from my YouTube channel, SebastiansAnimals (catchy huh?). I would like to state that the opinions expressed in this blog are my own and not in any way meant to be taken as the views of anyone else I may mention in these ramblings. Sebastian. March 2012.

Invert update 2 (and other news).


Well the original draft of this started with “Presently all doing well at Grant Towers”…. But, as you’d expect of me, things are going downhill.

 The Acromyrmex octospinosus have got alates again, not sure why this is happening but I’m not sure anyone knows. Maybe once it starts it is an on-going problem?  They only seem to be in the new nest chamber, so I could strip it down and not risk killing the queen, but I will try to be less invasive and offer more fruit and early morning checks to catch them out and about (and then murder them).

“The weavers Oecophila are doing well”, I’d written… But, maybe I shouldn’t write a draft but just post straight away. I had thought they were starting to expand with one large nest and what looks like a smaller satellite nest, but then I found the queen outside the nest surrounded by workers. The next day the same, and then she was wandering around on her own.  Not good.
                                                                              
I have posted a question on the Antstore forum
So will hopefully get an answer to why this may be.

My Catalaphyllia jardinei is looking a tad ropey the last week or so, it’s in a medium flow area in a heavily fed tank and I’d dropped off the feeding schedule lately.  A classic mistake with many corals when they start to do well, you ignore them, then they crash.
I’ve moved it into a smaller, shallower tank with more light that’s easier to access and will feed it daily so hopefully will see some improvement soon.  I really can’t kill this, it’s one of the corals that seem to do well but aren’t bred, just collected from the wild. BUT, although it’s easy to say you should only buy captive bred, this offers nothing financially to the countries concerned with trying to maintain their reefs. How much can they care about long term solutions when we take their environmental property and make money out of it instead of paying a little more and encouraging proper management of the reef?

If you enter “biopiracy” into a search engine it will come up with lots of things about big pharmaceutical companies taking plants from the rain forest and we all think they’re very naughty, but we rarely mention corals.
(Ok, let’s ignore that the corals and fish are flown over in tiny bags of heavy water…)

On a more positive note
I was also given another Polistes colony. 
                                                                              
These are housed in the same plastic tub but this time with no furniture. This species is doing well in other collections in more basic containers so I will mimic this for now.
The initial move was a pain as I had hoped to copy what I’d seen and stick the nest to the walls with gaffer tape. However the nest didn’t stick to the ropey old tape and it fell off. I then went back to super glue.
I will try not to kill these too quickly… (Maybe the person who gave me them just doesn’t like wasps and knows that I AM pest control……)

Although not invert’s I must mention Neoceratodus forsteri, the Australian lungfish, this species has captivated me since I knew how unique, how hard to come by and how expensive they were*. Stay tuned to hear more. Don’t touch that dial…
*Do you see a pattern emerging?

ANTS!!

I really like ants, there’s soo much variation in them that they appeal to me pretty much like “herps” or “fish”, the more you know the more amazing the diversity becomes.
I’ve kept a few species, some not too successfully including, Pheidologeton diversus,  these didn’t do well (read survive…) as the colony was way too small.
Solenopsis geminata, didn’t do well, I think because of initially a too low temperature so I gave them away to someone with warmer conditions. Polyrhachis australis, I tried my first colony in a mixed tank with Diacamma sp. but kept finding ants dead in a midden, I believe the Diacamma picked them off as they met them. My second colony did well until I moved them into a much bigger area and the started to produce queens and males which I think drained the colony and they faded away…
    
However, I don’t kill everything; a colony of Crematagaster sp.  I received from my ant store did too well. I initially got them hoping they would set up home in a Dischidia pectinoides the species of plant they had been collected in. However they dug under some wood and grew from there. I gave them to someone who had much more space so they could expand. He thinks they have now split into 3 or 4 colonies. 

Acromyrmex octospinosus;
I seem to be having luck with my leaf cutter ants, Acromyrmex octospinosus. These I received from Andrew Stevenson of the company Educational Displays, I have known Andrew for many years and have always had great colonies from him. My current colony I recently gave a new chamber to see if they either moved into it, leaving their old nest or just added it as another chamber. They very quickly started gardening in this one as well, nearly doubling the size of the fungus garden in under a month. They are collecting much more plant matter but producing much less waste, as it’s all going to use.

The only problem I have had with this colony is they have repeatedly gone sexual. A number of times they have started to produce winged queens, which if allowed to stay will drain the resources of the colony by eating the fungus but giving nothing back. I have been told that once this starts that the colony is probably doomed. (We once counted around 100 alates leaving the nest trying to do a nuptial flight).
The advice I received to stop this is to tip the nest into a tub so you can remove the winged queens, however after a while the alates remove their wings and are difficulty to tell from the actual queen. But if placed in a tub the original queen will soon by surrounded and protected by workers while the others will be wandering around, ready to be removed. But as I didn’t have the nerve to do this I pushed bits of fruit (mainly apple or grape) into the openings of the nest so that the alates could easily feed even if they didn’t leave the nest. Then, when, I noticed alates outside the nest I removed them. This is most easily done by turning the lights on suddenly. 

Oecophylla smaragdina
My weaver ants, Oecophylla smaragdina which I received a month ago are doing well, they moved out of the initial nest of 3 or 4 Ficus leaves onto a live Ficus pumilia as soon as the old leaves dried up.
However due to space restrictions I would like the colony to start living in a fake plant. The space I want to keep them in is very long and wide but no higher than around 60cm if it’s a real plant. (This is because the lighting will need too much space.) To see if this will work I added a few bits of the fake plant on top of the nest.
Within a few days they started to attach silk on to the leaves.
I have now added more of the fake plant nearby hoping they will move there permanently as the real plant starts to suffer from their actions.
Looking at posts on ant forums (by ant keepers, not by ants) it seems this should work. We will see…
