Ok i have this 80 gallon tank w/ 3 bala sharks and 4 uggly ass small cat fish.
oh and 3 big ass feeder fish(gold fish) :dunno: < they survived !!!the sharks didnt eat them and now they're hella big.........anyway here's my question....
this MOFO's are allways Hungry ...I feed'em like 4 times a day with: flakes/bloodworms or shrimp(cutted in small pieces) and the tank gets fucking nasty in like 3 days they eat all the food but ,they shit more then me=(
how can i keep this clean? do i need a big ass filter or how many times do i have to feed this bitches a day? they seem to B starving all teh time :banghead:

Dont know from personal experience, but a friend of mine had a shark and he just had to clean the water out with a good filter and clean the filter often.

You need a filter and you need to get some of those algae eater fish.

the tank gets all dirty from the rotting food they havnt eaten. dont feed em as much and see what happens
