Most likely your Oscars are fighting. Oscars usually fight with each other. As is your tank is not appropriate for even one oscar so they are probably fighting for territory.I have no idea on sex I've tried to figure it out it's just beyond me and they're in a 55 gallon
The problem is a 55 gallon is only 12 inches wide and oscars can get 12 inches or larger so it would be very difficult for them to turn around. Minimum tank size for 2 oscars is 100 gallons with 125+ being the reccomended size.Why is my 55 gallon tank not appropriate for an Oscar
Unfortunately cories are reccomended for a 20 gallon minimum but you could add a Nerite snail or 2, they are very good algae cleaners.The tank with that brown stuff on the Rocks is a 3-gallon it has a beta in it would I have room to put a couple Cory cats in there and if so would they keep the rocks and stuff clean?
You can great deals on here once you have 50 messages. Try looking in the BTSF forum just to prepare. Craiglist has some great deals as well.I understand when they get bigger I'll have to have a bigger tank for him but right now they're only 3 inches. And I couldn't figure out why they were saying 55 was not big enough for the size they are now. I know I have to get a bigger one but I've got time that's what I was trying to figure out if everybody was saying that don't have a big enough tank now. But I figured out everybody's talking about when they get big. And by the time they get too big for this tank I will have another one. Looking for a deal on one now.
That's real good to know I was worried about having way too many snails in a tank LOLI have nerite snails in four different tanks with openings in the tops, and none have left yet. I agree with the previous poster, I don't think they'll climb out as long as your water is good. And they are great at dealing with diatoms! And pretty! And they won't reproduce in freshwater, so you won't be overrun with snails
