Hi. L333 requires a high-protein diet. While young L333 may eat some vegetables, their diet should shift to meaty foods as they grow. They need bloodworms, chopped mussels, chopped cockles, or prawns. They don’t eat algae and won’t touch algae wafers. Just weighing in on Hypancistrus diets as the ar ...

Are there many gut analysis papers for this genus? I wonder what they are digging into in the wild. I figured larger insect larvae, but it could be snails or as wild as crustaceans. Do you think they are finding food in the substrate or in the "nooks and crannies" of a hardscape? My only experience ...

If you're concerned about the water hardness many Ampullariidae, apple snails are found in softer waters, they seem to be much more omnivorous so maybe are one of the many who get their calcium more from their diet. Maybe there is an ontogenetic change in their diets, it's never been studied in ...

I've got one, I got mine as an only individual in a batch of Parancistrus nudiventris. Not seen any others available or even others other then a commentor on my Youtube keep them. A UK store seems to have them but many of their photos are of Parancistrus nudiventris. All I can say about colour is ...

It is no doubt interesting from a behavioral aspect. These fishes are clear carnivores, morphologically and from the few ecological studies. Carnivorous species I've noticed generally have very mobile jaws but there are exceptions where jaws are reduced. There is a slight exception with some of the ...

Hypostominae, contains mostly territorial Loricariids. That includes Panaqolus and they do not share their caves either for females it's their space (could also be related to reproduction) but for males it's certainly for reproduction. If another fish is there many wont tolerate it. Sharing a cave ...

These distinctively marked Dekeyseria are D. picta. Makes it easier I think then identifying D. picta from what was D. brachyura.

As a database Fishbase is good but also for information it is a (very large) pinch of salt. Databases can be tricky to create with what you include and exclude. Fishbase I've found also includes information that lacks citations or the citation might not entirely back it up. The other aspect with ...

Definitely no shortage, I remember sorting through Bagrus, not sure I finished either. The size of some of those fishes.

Loricariids do get strange growths. Lymphocytis is the most well known but has never been proven to infect Siluriformes or other related lineages like Cypriniformes, therefore the research is lacking and I've tried to work out if it's due to a physiological reason or they are asymptomatic. So for ...

Sometimes we never actually notice growth and it is happening. There are other factors like diet and availability of food I'd explore. The availability is more of an issue for busy tanks and yours doesn't look too busy. I agree Hypostomus but other then the H. cochliodon group I'm not a fan of ...

I'm surprised this paper hasn't got more publicity. It's fascinating and kind of changes what we knew about the group.

Odontode size is generally seasonal in many Hypostominae and I assume most Loricariids, at least those who have large ones. But the common bristlenoses stopping might be a correlation, might just be coincidence. There are many factors that stop breeding, density does frequently get seen, I suspect ...

I think I understand what you are saying? Treating populations as isolated entities? I personally think that is a good idea, when it comes to individual populations individual populations can be as distinct genetically and morphologically as different species. In fish biology we don't really use ...

I would say it most likely would work. Although my only hesitation would be the size of the common bristlenose, the blue eyed variant doesn't get quite as big as the normal browns or the albinos but it might just be most people haven't had theirs long enough yet. The common bristlenose, Ancistrus sp ...

He's certainly not old. What are you feeding him? Anything faster feeding in the tank? The fact he is skinny is probably why he isn't spawning. When was the last time you wormed him and since have any new fish been introduced? I don't think worms is normally why a fish is skinny but worth asking.

I seem to remember there have been others but none have been caught alive. It's likely these fishes were only introduced during the summer, one really doesn't look in the greatest health either.

So sorry, Ancistrus can be a very challenging genus to keep. Once that skinny it really depends how long they have been like that. It's about getting anything in them but after that the healthy diet. I do suspect there might be a use in having them in with other related fishes who willingly feed if ...

I agree on the Hypancistrus sp. I don't think L471 can be identified from L201, the locality I don't think entirely matters unless this can be studied? I also don't know the geography that well. L471 definitely gets larger in size then original estimates, they aren't the dwarf they were sold as. I ...

This is more of a Hypostominae issue. The advice I'd give is firstly keep similarly sized species and individuals together. While as juveniles it might seem okay but as they mature for many territoriality increases but even more so their size, bulk and what damage they can do does increase. I have ...

I just noticed GBIF and Inaturalist were lacking a lot so I think it varies and honestly it seems in general you have to go direct. Several times I've tried locating specimens particularly and just ended up going to the museum catalog if they have one. Then for geographic data I do think there is ...

I worked in one of the oldest MA stores and it hadn't renovated for since it opened so 30 years, those tanks many were standing till the eventual refit but some had to have various work on I was told just to stand. Some there was also a leak between tanks in a system. Another store I worked at ...

Yes, it's a really black even when stressed with the white spots. Shame there weren't anymore but I assume it might be a fish that pops up occassionally.

Found something a little bit more uncommon. I believe it was imported as Ancistrus sp. from Brazil but this was the only oddity from the batch. I think Lasiancistrus sp. 'L033' but the spotter differs to me, and not sure that L number is truly different from L337 but L numbers being L numbers... For ...

In my opinion there are a lot of variables when it comes to aquariums so it's difficult to make an estimate and apply. Quite a few things aren't accounted for and the values for water changes I personally think are a real underestimate to what the hobby actually does. The fish food estimates I'm not ...

As a teenager I do remember the fishes gasping at the surface when using incense. Not sure there are any studies on it but I don't allow it or use it anywhere near the aquariums, or anything one might burn such as candles, smoking or any fumes such as aeresols. I find it easier to have the aquariums ...

No idea if the images will work, been years (maybe over 10 since I've used a forum like this). Partially influenced by Shanes post and seen quite a few people in the past with pet plecos. I thought I'd introduce one of my fishes, she has no name I don't generally name things. I never really had them ...

I've owned a pretty good sized individual, the only time I could measure the fish at maximum size was around 15cm SL but later grew I assume a little more. They can throw their weight around but I don't think they do as much as true Baryancistrus. Visualising footprint either the 90 or 120. Gives ...

Diets in Loricariids are awfully patchy in the literature. Some we have to extreme detail e.g. Panaque/Panaqolus or detailed gut analysis e.g. Lasiancistrus caucanus. Otherwise it's often vague with generalisations of taxa so there is a level of ambiguity, it's not like some mammals where we can say ...

There are three wormers, honestly I've never noticed any difference between them. Flubendazole, praziquantel and levamisole. Each does target particular different taxa of parasite but identifying which is causing issues is going to be challenging. Generally it's best to treat once then treat again a ...
