I'm only going on what people have told me (therefore may just be repeating misinformation), but I'd thought that CW021 had near-parallel black lines, whereas in axelrodi the lines converge (as can be seen in the bottom line in Frank's photo of an adult fish).

I thought this was going to be a discussion about peer reviews of scientific papers!

any updates on these Mats?

I'm assuming (but don't know) this fish is a recent import, so I'd say it's unlikely (it's entirely possible the fish was a trade-in, but I'd have thought this was less likely).

I'm unfamiliar with American tank dimensions, so I don't know what footprint a 40g breeder has. My 36 UK gallon tank has a footprint of 4' X 1' and has 3 males and a female in it (not the sex ratio I aimed for!) and they're fine- the males even tolerate each other feeding on the same piece of courge...

I'm hopeless on elegans-complex corys- I think Mats is right in that it's a species similar to elegans, but there are so many similar-looking species in this complex that you really need someone like Ian Fuller (Coryman) to give an ID.

I'm not prone to sticking my neck out on here, but I'd say this is a new species. the elongated mouth doesn't look like a deformity, to me. I'm not sure one way or the other on head shape- it is markedly different in shape from any of the nigrolineatus -type Panaque - the snout and mouth seem very ...

I believe you should still feed a variety of fresh greens. I'll agree with this- I'm a bit lazy and tend to just feed courgette and cucumber (in addition to algae wafers/spirulina granules and flake, very occasional catfish pellets and frozen bloodworm), but if they're fed a variety of vegetable fo...

assuming these are the same fish in the thread, these are better pictures (just following Mats' instructions)

Yes, but HAVING kept a fish doesn't mean it's necessarily on the My Cats - and the experience may still count... true- I've got a few from the distant past (1980s) I never added due to not being sure of dates, but anything recent would be there even if I killed them off (under "kept" rath...

Who said it was on Richard's my cat list? noone did, but I can't think of another way to guess otherwise! I'd thought that, to do a CotM article, it should be a species someone has kept, preferably reasonably successfully... Plus I've gone through all the African families I can think of and nothing...

I think Jools has ruled out SA fish on this- so I'm assuming that it's an African fish we're looking for, but the only one that's left that Richard's got on his "My Cats" list that hasn't already been a CotM is Lophiobagrus cyclurus, which I can't get to fit the clue.

Jools wrote:not something that belongs to a family that initially sounds a bit like the coffee I am drinking.

to me Jools is saying it's NOT a mochokid.

"Pseudonem" sounds a bit like a pseudonym, which, stretching it a bit, could be conceited. It's a fish Richard's got in his "My Cats" page, and the clue didn't specify a continent as far as I can see.

???

I'm struggling to have any idea of a non-mochokid that Richard would write about...

Verging on cool but not extremely cool for me- most definitely not subzero. Nice that it's distinctive (if a little odd-looking- certainly wouldn't win any beauty contests), and non-predatory compared with others cats its size, but a bit on the timid side for a mid-sized cat. It looks a bit too much...

My oldest tank is just over 30 years old (although it wasn't running for 17 of those) and definitely not mint- it's got scratches on the outside from transferring it from Sheffield to Bristol, back to Sheffield, up to the loft, down from the loft, and from Sheffield to Aughton- it's not suffered scr...

Only 820 times on my home PC- would be in the thousands on my work PC, but that version of Firefox lacks this particular functionality.

There's also a current seller on Aquarist Classifieds with the same username as that post on MFK.

300 litres sounds too small to me long-term- my tank is 675 litres and I'd say that's a bit small for my sailfin (I bought the fish before checking the internet- none of my 1980s books suggested that they grow to 2 feet long). Older sailfin and common plecos have a slight reputation for being aggres...

I agree it's a big difference between collecting fish yourself and getting them through a long chain of suppliers. And of course, if you drive for a couple of hours, catch some fish, take them home and put them in a tank, they are (probably) a lot less stressed than fish that has been flying halfwa...

Pleco and acrylic eventually equals a tank thrown in the trash unless you are keeping something like Otocinclus , or as NX7 suggested, reophilic loricariinae.. From this, I'm assuming that even non-toothed plecos such as Pterygoplichthys and Ancistrus do enough cosmetic damage over time to ruin acr...

ditto- mine would look like that if she went on a diet for a few months!

At least this one lacks the head deformity- shame it's a hybrid as it's an attractive fish.

If sunlight is a problem, perhaps replacing the rather see-through hose with one that is either darker grey/brown or, like Eheim, green? That's a reasonable suggestion- definitely worth me keeping an eye out for suitable opaque hosing. I don't actually mind (too much) that section clogging up, beca...

There is extremely little data on lifespan of wild fishes in general. I would say that they are more likely to live long in captivity than in the wild. I remember seeing a website with oldest recorded fish ages for different species in captivity (in some cases unsubstantiated), but annoyingly I can...

I have not had any TetraTec Internal filters, so I can't comment on them, but I have two EX1200 and one EX700 - and they work really well. Sure after several months of neglect, they tend to be a bit mucky inside, but flow is still good in my experience. Perhaps it depends on what fish and/or food i...

I'd be a bit wary of comparing flow rates between companies- for example I've the misfortune to have four Tetratec filters (EX700, EX1200, IN800 and IN1000) and I don't think the flow rate is 10% of what's claimed after a few months' worth of running (the two internal filters are particularly dreadf...

My local club had a tour of the back rooms of Bolton Aquarium a couple of years ago (September '07) with Paul Dixon- very interesting; for a public aquarium I was impressed with their breeding/raising tanks for a large range of fish. The baby C112s and C113s looked stunning, plus I came home with 5 ...

Many thanks HH- that's pretty much exactly what I was looking for. I normally check the Taxonomy/Science news but must have missed that one.
