Hey, Im new to the hobby and have been surfing your site a long time getting valuable information about everything.
So I decided I would join to ask for some information and opinions.
I have a 4foot fresh water tank. **could not afford the setup fee of salt water, so this is just to start out**
1 Salmon tail catfish, 1 rivulatus, 1 Albino tiger oscar and 1 Bala shark.
The oscar was from a friends tank that was getting beatin up, so he is a bit larger but a sook. the others are all about the same size and bought from different pet shops around town.
When I feed them, the oscar is straight to the surface to eat. the catfish is happily eating the food that is left on the ground, along with the sinking green pellet things i bought specially for him.
But the shark and the rivulatus will not come to the surface to eat. the shark is acting like a bottom feeder sucking up the food off the rocks. and the rivulatus is just eating the food that sinks.
I have tried a verity of different foods and they eat all the different foods like flake, pellets, blood worms, shrimp.
I have tried taking the oscar down one end of the tank and feeding him, and then feeding the slightly smaller fish at the other end, but still they will only eat then the food when it sinks.
friends of mine have all these fish and said they are faily easy to care for, and they all eat off the surface so thats why i am a little worried.
also it is a bit of a pan not being able to see how much wast food there is.
the tank is about 6 weeks old with a good balance of everything and no poisoning of the sort. *the local pet store done the tests for me* but they are unable to explain why the fish dont eat off the surface.
any suggestions would be great.
