Subject: Colombian sharks


can please you send me any information that you have on colombian sharks

thank you,


Latin name: Arius Seemani. This fish grows quite large, but is well adapted to a large-fish community tank. It likes salt in the water (brackish). I would say about 1 teaspoon/gallon as a start. It enjoys a somewhat alkaline ph around 7.5. They like the water a bit warmer than most at around 27 degrees Celsius.

The main thing here is don’t try to put this fish in a small tank. It will outgrow the tank quickly. These fish also do like to be with companions of their own kind, say perhaps three to a tank. Lastly, don’t try to create a community with small fishes, as they may be a meal.

I hope this helps.
