Tridensimilis brevis

[Richard B]

Whilst in London today, although I didn't have much free time, I did pop in to Aquatic Design Centre. I nearly missed them. They had a nano set up with Tridensimilis brevis . Tiny little things but they looked really good. Given they may be suitable as aquarium fish, there's an opportunity for someone who is after something different.

Tridensimilis is definitely an oddball and one of the very few parasitic fish that can be kept, but it's also 1 for the species tank; this fish cannot be trusted with any other fish; small o large
sooner or later the other fish will be harassed and mucus and skin will be rasped.

they're not as bad as Ochmacanthus, but nearly so.

I didn't get a chance to talk to the staff about any problems they'd encountered, feeding, how long they'd been in etc
There were some tankmates though: a few

Hisonotus leucofrenatus

& a load of what looked similar to pangio doriae (although these were wizzing round the tank so i couldn't see them properly)

There were some tankmates though

There should, otherwise the Tridensimilis would certainly die. Although I think the staff is unaware of the feeding habits of this catfish?

[Richard B]

I'm a tad confused - literature seems to suggest these would be fine in a species tank as they will feed on tiny live food (bbs, daphnia etc)

[Marc van Arc]

Personal experience tells a different story I'm afraid.....when "provided" with tankmates, they'll definitely prefer them over tiny live foods.

I think you can keep them without a host, but then you must feed often and only meaty foods of the frozen variety

they will not accept any flake.

bloodworms and the like is the best.

they're not plancton feeders; their mouth is designed to rasp, so they can't feed on BBS.....

but they do accept bloodworms (red mosquito larvae)
