I was looking at some Crocodile Fish that they had at my LFS, and they looked pretty cool, I did some research, but I can't find anything which really helps, so I thought I might try my luck on the forums

These guys, from what I have found, require at least 30 gallons, grow about 6-7" and are carnivores... That's pretty much all I've found though, any other info people could provide?

Like...
What can I feed them?
What size fish can they be kept with? (minimum size)
Is there anything special they need? Like a certain PH.

Pretty much any info could help, cuz these guys look really cool, and I wouldn't doubt that they'll go fast!
 
With google, I found that they are hard to get off live foods and are ambush predators. They require low pH in their tank, as they are found in asian black water. Apparently, they are very sensitive fish and can suddenly wind up dead for no reason. Lots of decor needs to be in the tank to make them feel secure and to help them with their ambush qualities.

As the poster said above me, Google does wonders. It took me less than 2 minutes to find this info. :)
 
Man, i googled it and couldn't find anything, all i found was info on the saltwater version, or freshwater crocodiles... there's one site i know of that had some info, but nothing i could really use
 
They are very cool. They are regarded to be quite difficult to maintain. Very difficult to get of live food. Brine shrimp, River shrimp and small fish.

They could be kept with anything of small size that 1. isn't small enough to get eaten and two isn't aggresive or pose any threat to them.

They prefer a softer, lower PH environment. PH 6.5 - 7.
 
Pikeheads are notoriously difficult to keep as they have very low immunity to bacterial infections due to their native blackwater habitats which are so acidic that bacteria cannot form there. To keep them healthy in captivity they need a pH below 5 but then you cannot grow the bacteria needed to perform the nitrogen cycle in the filtration so you need to start filtering with stuff like zeolite which removes the ammonium from the water before it can become part of the nitrogen cycle, but this needs regular changing before it can become saturated and allow the ammonium into the water.
