Fish Profiles

Unread postby KarthikC » Mon Jun 09, 2014 1:34 pm

Hey all,

Hope this is not a repetition. Let me start with my all time favourite fish- Channa.

Characteristics: Very shy till it fully adjusts to the aquarium environment. Shows full coloration after about a month, dont lose patience. Slow swimmer, but can be lightning quick when it spots food. It can bite if it mistakes your finger for food.

Diet: Many channa are insectivores in wild, feeding opportunistically on fish, whenever they find. They prey on worms, snails, insects and shrimp in the wild. Live/feeder fish should be the last option you should be considering. Probably the best foods in captivity is frozen shrimp and blood worms. If you can feed it live earth worms, you should.

Tank size etc: Suitably decent tank size, with lots of hiding places is preferred by the fish. It doesn't move much, however, ample swimming space should br provided. Depends on the species, actually. A pair of golden gachua, for example, can be housed in a 2x1x1 tank. They are labyrinth fish, so access to the water surface, and preferrable fresh air about that is must.

Tankmates: this is people's favourite question! Please don't mix Channa with other fish. Species only is preferred. I had a loach in my two feeter and is impossible to catch without taking apart the tank. This is what the channa did to it

They're master predators and strategists. If you really want to mix, please get a fish which doesnt fit in it's mouth. Also, channa doesnt like new water, while selecting tankmates (which i dont recommend) keep this in mind.

Full shot of my channa:

Hope I have't missed out anything. Looking for suggestions and fish proiles from all. Please keep it to really uncommon fish. :)

Cheers,

Karthik

Asian Stone Catfish, Hara Jerdoni.

Characteristics: Relatively poor eyesight, won't even respond to your hand movement outside the aquarium or inside. Prefers to rest in shady areas, prefers low light. Very sluggish swimmers may not do well with aggressive fish. They grow upto only 2-2.5" so preferred for nano tanks. May distrub plants/substrate while feeding, so if you're choosing this for a planted tank, better to have the plants well rooted before introducing them to the tank. They're also sensitive to co2 and prefer well oxygenated waters. Temperature preferred by them (at higher temperatures, they might not even feed :( ) is 20-24 Deg. C. Good practise to keep them in a group of 3+, althout not a mandate.

Diet: Here's the Challenge. They just wont take pellets, unless they've really spent 2-3 months in your tank. That too, is pretty rare. In the first batch I got, the fish used to go for pellets very very rarely. Food that you must feed this fish is preferrably live blood worms. Frozen (in the red form) will do. Even though it looks like a mini-pleco, it's NOT an algae eater. Strictly Carnivore :)

Tank size etc: Well suited for the Nano tank. Prefers less water flow. I would really suggest you keep this fish in a mildly planted tank without Co2 or any hifi stuff like fertilizers etc.

Tankmates: Very very docile fish, doesnt fight back when attacked. From the feeding perspective, choose less "greedy" fish which leave some food to reach the bottom. Or else, you can drop the food once lights are out. Shrimps might be attacked after they've molted. Shrimplets are snacks for sure :D

Hi, thanks for pointing out. A group of 8-10 should be OK in a foot cube. You may be considering other fish with this, hence the number is limited to ten. Other fish from same area (of collection) will be a great addition to the tank. I have a bumblebee goby and Rasbora Maculatus (not indian native) along with this 5 of these fish.

Cheers,

Karthik
