Hey everyone. This is my first post on this site. I've been lingering in the shadows for a while though. About 6 months ago we bought a 10 gallon tank so that we could get some fish to entertain our kids. We bought a Blue gourami and an Upside down catfish. A few weeks ago my father gave me his 29 gallon tank so I now have that set up.
Up until tonight I had (purchased before I came across the info on this site):
1 Tiger Oscar (about 3.5" long)
1 Blue gouarmi (about 3.5" long)
1 Upside down catfish (about 1.5" long)
1 Chocolate Pleco (about 2.5" long)
1 Dragon Fish (about 7.5" long) - My favorite
After purchasing him I did my research (first mistake), I see he is very hard to care for and to get to eat. I feed him blood worms and I have added the appropriate amount of salt to the tank. Also I know he can get rather large but I plan on upgrading to a 75 gallon or larger tank next spring.
2 Snails (One gold and one black)
Up until tonight the Oscar has got along with everyone just fine. But tonight he started biting the others (he has always chased them but never bitten). I have isolated him in the 10 gallon tank for now and will either give to my father to put in his 55 until I get a bigger tank or return him to the fish store. I love the Oscar but he's become quite aggressive and he hogs the food and I would be afraid that the others were not getting enough to eat.
So this is basically where I am at.. now on the the question. I currently have an underground filter with a dual air pump to help with filtration as well as the filter from the 10 gallon tank. The filter that came with my 10 gallon tank just is not cutting it. I need a recommendation of a decent filter preferably for up to 75 gallon tanks as I would like to over compensate just to be on the safe side. I was looking at possibly getting the penguin 330 which is good for up to 70 gallon tanks. Any thoughts?
Sorry about the long post but I wanted to introduce myself, and ask about the filter.
