Observations: storms and activity in Y. modesta.

Observation:
Ol' Gustav came by the other day and shook things up: rain and changes in temp and barometric pressures etc...
Aquarium temp went from 31.5C (i know, bad, but not much i could do) and everyone getting a little listless down to 27-28 or so over 24 hours.

Blue-crew went nuts- but not in the usual annoying-everyone way, just among the three largest (2x male? and 1x fem?) of themselves. Breeding in the spp is climate/rainy season related back in the old country, so it makes me wonder if we're seeing something of particular interest for as they get older.
Everyone's calmed down now, even with the tail of Ike still making a mess.
And yes, i still owe you photos of the caudal peduncle spot. Remind me over the weekend.
Thought you might be interested.

Haha, I was going to give you a nudge on the caudal peduncle spot, Andyroo!

I will also have to dig out my pics.

Interesting report re: their behaviour during temp & barometric pressure changes. I take it that if anything did *happen* you have other fish in that tank that would predate on eggs?

Re: egg consumption, i don't know. The cat might be a little big, the goby's too busy doing goby stuff, the pleco's a bit clumsy and the rest are off the bottom. With the hair-algae there's certainly lots of micro habitat. The loaches make sure there are never any little rainbows, but who would eat loach eggs? I'll keep an eye out, but the loaches aren't very big yet.

As requested. Sorry about the cropping and (dark) colours
Any thoughts on ID of the little white crustacean living on the stones? The loaches used to eat them, but seem to have out-grown it. Eventually i'll collect one and take it to the lab to have a micro-look.

and

Caudal peduncle spot is even ringed. She's grown a bit since this photo.

the modesta's are in great condition bud, as to the pot i suspect it's just a different marking than the other modesta, we can see unusual patterns in most of the botias we keep.
beautiful fish though.

Those are excellent pics Andyroo (you should post photos more often!

). I have found some pics that show a mark on the top of the caudal peduncle, but in most cases, the mark does not seem to be quite as rounded as the one on your fish. Do you find that the spot ever fades and darkens, or does it remain dark all the time? In some of the pics I found, some seem to have the mark, others do not (all adult fish). And the intensity of the mark seems to vary.

Sadly most of my pics of this species do not show the caudal peduncle off properly, as when I approach with the camera, the Y. modestas always seem to want to dance and show off their bellies instead.

Would be very interested to see pics from others who keep Y. modesta and hear their observations on 'the spot'.

Emma,
I'd have to get off my behind and clean the glass more often to send more photos :) Particularly if you're going to follow mine up with yours... spectacular. How long are those fish? Do the tails grey-out with age? My big(gest) girl is still only about 8cm long.

The spots do seem to be changeable. The smaller ones have a darkening at the top that goes down- more like a dark slash then the distinct spot of the big girl. I wonder if it is a dominance/social characteristic? Fish still in the shop in Kingston (unhappy, bare tank) seem to have at best the slash, most with nothing.
I'd increase my school size to take these others on but they're quite costly and i'm not sure if my system should take another 7, but i'd feel bad about leaving only a couple in the shop. They're not selling- have been in this shop since before i got mine (Feb) so i might make an offer next time i get to the city.
The wife wants to try Clowns again to round out the Botia school with a little more colour. Not sure how good an idea this is, though Blue Crew seems pretty good/docile with the angels, gobies and cats.

Would they be freshwater limpets? http://animaldiversity.ummz.umich.edu/s ... 9.rjb1.jpg
My SAE eat them, or at least did when the SAE were young. They either cleared out the tank or still eat them.

Two of my Modestas has a slightly broken Black spot on the top of the caudal peduncle. I'll have to get a pic of it at some point in the next day or so.. I think they are both Ashleighs old Modestas so she may have a photo or two.

Sorry for the quality, best I can do with my camera speed and super fast Loaches who won't keep still.
There are 5 in all who have significantly noticeable black spotting on them (possibly 6 I can't be sure with one of them) most are on the top of the caudal peduncle whilst one has one at the base of the dorsal, another has one just behind the head

stuning reds on your fish bud, the second pic is as clear as a bell.

i always like seeing other peoples fish.

As Mick said!!

Wow, excellent colours Doc

Andyroo, there's been heightened activity in many of the tanks over here in the UK. It may well be down to the unusual weather we've been having, though nothing like you've had there.

Doc · Post by **Doc** » Wed Sep 17, 2008 6:32 am

Ta Mick and Gareth. I'll admit that the (only slightly

) better specimens in my group are the ones I rehomed from Ashleigh, hers are deeper bodied than my original 6 but mine are just slightly longer in the body.

I definitely notice differences in their behaviour during particularly heavy rain and the odd thundery weather we have. They are much more animated and swim around in a much tighter pack.

Mine on the right, Ashleighs old one on the left.

Wow!
What do you feed 'em to got those reds?
Re: the limpets, could be. But a limpet is a little pseudo-snail critter, and these things don't seem to move and leave a ring when your scrub 'em off the glass. More like some sort of barnacle. I'll look up the limpet properly and get back to you.
