Appearance: Perhaps the most widely variable fish of the genus, L-333 is a name designated seemingly to any such fish that is of the king tiger group that does not have an obvious designation…needless to say, this number is in dire need of cleaning up, but there are a few general guidelines to follow; at least pertaining to the fish first listed in DATZ. This animal is somewhat more compact with larger fins relative to the body than other similarly colored animals. Furthermore, the patterning is less discrete than other vermiculated animals. For example, while the stripes of L-66 generally maintain a relatively uniform anlge along the flank of the fish, thus giving the effect of multiple parallel lines running in a repeated fashion, L-333 markings often stray in a haywire fashion, and may oscillate regularly (forming “squiggles”, if you will). However, markings such as these are a somewhat less reliable way to identify a fish in question, and again, this number still is in dire need of reclassification. It should also be noted that these are very large animals, topping perhaps even L-66 in terms of sheer length and girth.**

Sexing and Breeding: A lovely looking Hypan that can be bred at higher temps (30c) in the home aquarium

Diet: An Omnivore that leans towards a meatier diet, so foods like frozen bloodworm, Carnivore pellets, Earthworm sticks, Tetra Prima should be provided It doesnt hurt to also introduce some veg once in a while to their diet.

Hypancistrus youngsters may require a more vegetable based diet according to Back to Nature Lnumbers book.

Just thought I would share with you all my L333 set up.

Standard 30" x 12 x 15 80 litres

Eheim (of course) external 850 Lph fitted with difusor
Maxijet 600 Lph Powerhead.
200 watt heater.

3 Adult wild caught L333. 1 male and 2 females. These are the biggest Hypans I own with the male almost 5" TL
5 Juvenile Corydoras Metae
Assassin snails


TDS 150
PH 6.8
Nitrates 20
I dont test for anything else

Normal Hypan breeding applies, Plenty of good quality water changes allthough because of the high temperature I do smaller changes to avoid a big drop that could shock the fish.

All 3 adults cave and when the male wants to spawn he will visit the cave the female lives in. Sometimes the female can be trapped for anywhere upto 2 weeks but normally a few days. They produce between 20 and 50 eggs depending on the female. The eggs are really large at maybe 4mm.


These are the only pics of the adults I have which were taken before I moved them to the breeding tank

Carlsberg don't make external filters but if they did then they would make them just like
