Check the Chaetostoma species in the cat-e-log

Any of the lake species of synos would work in a Malawi tank but i'd avoid riverine species - particularly nigriventris.

Filament barbs get to 6"+ & can be quite boisterous, lots of people suggest you need a bigger tank with high oxygenation for these - congo tetras would mix ok but given max sizes you'll need to carefully think about stocking levels for 2 shoaling species. Paradise fish are a slower species ...

Pic above looks genuine but I've never seen w/c smaller than 10cm SL & never with the juvenile spotting - better catch methods may have changed this. I wonder about the costs involved in Neil shipping to the US - an email to him would get an answer & I'm sure he'd be interested as if not, so...

Are these 'white polli'? the undescribed Zambian species rather than true polli?

I've not had problems keeping black or harlequin lancers. pH 6.6-7.2 generally, nothing special, good filtration & aeration, smaller set-ups with small dither fish or very different bottom dwellers (mochokiella). General aquarium foodstuffs plus shredded earthworms, minced prawn etc

One member of a genus should eliminate hybridisation as indicated by Jobro above

I see Congicus about every so often but not too frequently & quite often labelled Notatus - but easy to tell apart by barbel
length

Congicus would work fine as they are slow growing, but more importantly a very gentle syno

Although these are slow growing they could reach 20 inches long so your suggestion would only be a temporary home for them but in the short term would be ok. Rocks are less important than wood but great filtration & good water management are vital

Welcome to PC

I've only ever seen 1 Aterimus ever in my life (which was in the late 80's) & everything else is a juvenile eupterus or hybrid - even most photos on the net are wrong - therefore I believe chances of obtaining this species is nil. For a 4x1 foot tank i'd go for a smaller species - nigriventris, ...

Welcome to PC

I'm not sure I can find anything suitable from either the Esmeraldas or Tumbes to suggest. I would say it would need some cover for cats to go with Green Terrors & it needs to be either quite heavily armoured or boisterous & swift - so something like pteradoras or pseudacanthicus (armoured) ...

Mystus species - possibly gulio

Does look similar to (though definitely isnt)

Luciopimelodus pati

. More photos might help, but hopefully someone else will chime in with an ID.

Adipose looks wrong...

It does look like a hybrid. Anyone else?

I only ever had one (when I was in the trade) about 10" TL. Delicate looking creature with 'normal' nose. Not a fussy eater at all - prawn, cod, squid pieces etc. Kept in a 6x2x2. Never 100% settled as it was easily startled & was 'uncomfortable as it's barbels were pretty much always in co...

I wouldn't wanna go any smaller than 5 foot by 30" wide - preferably bigger

Welcome to Planet Catfish

Some doradids & synodontis (like Polli) will eat small apple snails. Neither are native to North America in fact no native North American catfish eat snails. Adding non-native species to a habitat is not only a bad idea it is most probably illegal

Pretty easy IME but as above - very high oxygenation, good water quality. Not fussy on feeding & mine were kept at room temperature without a heater in the UK

Sounds interesting - is a pdf available?

Thanks as always

Masses of aeration & they really need a bigger tank - what filtration is there?

Synodontis Eupterus

I am going to be disagreeing with Richard on this one, I think lucipinnis. Birger They could well be & probability says they are likely to be but at 6-8cm SL or TL I'd expect slightly more irregular blotching. On the lucipinnis I see regularly the rounder blotch/spots become more irregular at a...

Headshape is wrong for 'white polli'

Good advice on quarantine - I'd also chip in that now Walmart have sold these cats that were suffering, they'll just get another load in & perpetuate the cycle - if no-one buys them, they'll stop stocking them. Are Walmart accountable to any licencing body to sell livestock? That is where we sho...

What size are they currently? about 6-8 cm The body spots are fairly rounded & fairly regular. At the size you state, if they were Lucipinnis I'd expect to see much more irregular blotch type markings, therefore I'd suggest these are immature petricola - one of the regional variations. They do ...
