Tank size for 1 Oscar

  • We are currently upgrading MFK. thanks! -neo
I grew my red Oscar (in my avatar) from a 2" baby into a 13" brute in 2 years in a 75GL with 2 fluval 405 canister filters. He was always kept alone with 80-90% water changes 1 a week and a good pellet diet with peas, fruit & night-crawlers mixed in as treats. They say 55 is Min I disagree I believe 75 is min and a 90 is better again because its the same foot print as a 75 (48"x 18"). You can't over filter a big Oscar tank they are very messy fish.

Thank you! Coming from a lone Oscar fish keeper. This really helps! :) Btw, if I cannot find the brand and model names mentioned in oscarfish.com. What should I be looking for exactly in canister or HOB filter? I get that I need twice of these.
 
1 Oscar in a 75, a aqua clear 110 (1x) should be good, I ran that exact setup for around 8 months.

Hey sir, what happened after 8 months? Did you have to add additional filters?

I do agree that one AC110 would be enough for that set up. I just tend to prefer two filters for peace of mind in case something happens to one of them. But two probably would be overkill. I've kept a highly stocked 120 running with 2 AC110's for a couple years with no issues.

Hello guys,

I did some research and I found this canister filter readily available in one of our leading pet stores. Please help me in deciding on what model should I get and if it's really necessary I get 2 of that model. (Setup: 75 gal tank with 1 baby Oscar)

Thanks! I'm really confused if I should get or 2 filters. It's difficult since they're not cheap. :(

2 filters IMO is the way to go. I'm not familiar (never heard of them) with "dolphin filters" so I cant comment on them. What about using EBAY and finding a more reputable brand, Fluval, Eheim, Marinland or evan Filstar? If you have to use Dolphin I would use 2 C-1000 minimum. you could start with 1 now and purchase the second one in few months.
