Pseudolaguvia virgulata in my tank, I want to see whether or not it can be kept sucessfully!

A change of substrate perhaps??? What kinda substrate is found in its habitat??

The natural habitats is formed of pebbles and those rocks/stones (collected from its natural habitat) i kept with. If aeration is good i just think they can survive well, I feed with tubifex worm (dried). I kept Acanthocobitis botia, Garra sp, Botia dario, Amblycep sp, Glypto, Devario aequpinatus, Badis sp and very small sized Mastacembelus as their tank mate.(Some might be odd)

They might be happier if you could give them some live food.

You think they will get enough to eat???

Silurus hits the nail on the head here.

They might be happier if you could give them some live food.

I have found that without live food in their diet, they tend to get hollow belly and waste away.
The live food that I use is: cyclops and sifted daphnia, grindal worm and If they are housed in the same tank as other compatible bottom feeders I offer micro worm at least once a week. This means that 'if' at times they do not get enough food, the smaller fine microworms are just about too small for anything larger than themselves to easily feast upon.

One live food to be careful with when feeding to small Pseudolaguvia is newly hatched brine shrimp.
Only feed a little; yes the catfish may be seen greadily feeding upon it, but it has a tendancy to constipate them if given to them in quantity.
Which usually ends in their death.

Thanks all, very informative. I will follow the same.

Based on my experience, you might need to target feed them when you keep them in a community tank such as this. I prefer to keep my Pseudolaguvia sp. with similar finicky feeders like Dario sp. If you don't keep them well fed they won't last long.
