Okay, I know this is like my 3rd thread about the same discus aquarium, but it is now starting to come into place. Now that I have everything figured out I just want to share with people my decision.
I have decided that 100+ aquariums require too much water change maintenance and are expensive, so I have decided to go with a 90g aquarium. To do 20% water changes on a 100+ gallon tank would require a 20 gallon storage tank somewhere but a 90 would require less space. 90g are also more proportionate and "show tank' styled. Also it is easier to fit a 4ft tank in my house than a 6ft one!
A smaller tank means a smaller stocking list, therefore I have once again (for the millionth time) revised my stocking list, so here it is:
- 6 discus
- 2 german blue rams
- 1 twig catfish
- 12 cardinal tetras
- 10 rummy nose tetras
- 8 hatchets
- 8 sterbais cories
Lighting: T-5 lights
Substrate: 1" peat moss + 2" sand
Water: 75% RODI + 25% conditioned tap water
Plants: Java moss+Java Ferns+Anubias+Amazon Swords+Dwarf Hairgrass+Amazon Frogbit+Dwarf Baby Tears
Fertilizer: Seachem Flourish
Filter: Depends on whether or not one comes with aquarium
Heater: Depends on whether or not one comes with aquarium
Accessories+Decorations: Feeder, RO, Driftwood, River Rocks, Slate Rocks
BTW: I am planning on buying the aquarium second hand. So my plans may slightly vary depending on the deal I get.
I am assuming a lot of people are awaiting pics and they shall come within the next month or maybe 2. But hopefully within the next month :)
Sounds amazing. I have no idea about which types of fish go well with discus but i'm a big fan of them.
Thanks :) I love discus too. I can spend so much time watching them at the LFS! I think this aquarium will be gorgeous :)
Dylan, my only comment concerns the lighting; the fish list looks good for a 90g.
If you have a dual-tube fixture, with T5 it should be NO [normal output] not HO for a discus aquarium. These fish come from quite dark waters and many have written about them being more relaxed with subdued lighting. Two T5 NO or two T8 tubes will give you good plant growth (see my 90g for proof of that) and with floating plants it will not be bright. As T5 and T8 tubes do not fit the same fixtures, you need to know which before you buy; and T5 NO tubes do not seem to be that readily available from what others here have commented, whereas T8's are everywhere in very good light spectrum.
Actually I do have a second comment:roll: on the filter; you don't mention any because it depends. A canister is the best for what you are planning. Discus also prefer minimal water movement, and I believe canisters are the best filter system for large planted aquaria. Most now have variable flow valves as well.
Concur w/ Byron. My discus tank has a nice cover of floating plants and the discus prefer hanging out right below it. You may want to provide some overhead cover as I think it makes them feel very comfortable.
I was planning on using amazon frogbit as a cover for the discus and hatchets mainly, but also for the other fish that like low light.:)
I am planning on buying the tank second hand, so if the tank comes with a T5 fixture, T8 bulbs wont fit right? Would the floating plants soften the intensity of the T5 lights or would it still be too bright? And speaking of floating plants, do I have to keep the water level lower so the plants aren't to close to the light?
Most aquariums I have been looking at have either rena or fluval canister filters, so I am not worried about that. It would really suck to have a 90 gallon come with a little HOB filter :)
One more comment. I have noticed that all the german blue rams in my area are in harder alkaline water. They even keep them with kribs at one place. Would it be a good idea to put the rams in a 5 gallon quarantine tank at the same pH they were at when I bought them and dradually lower hardness and pH by adding RO water into the water changes? The same applies with most of the places that sell cardinals and hatchets. Or could I just use the drip method of introducing them to the tank? OR I could put all the fish that are currently living in harder alkaline water in the 90 first, slowly drop the pH and hardness and than add the others like discus and farlowella, etc.
I just asked this because I heard many stories of peoples rams dying because of going too quickly from hard to soft water.
Floating plants certainly help to reduce light, and there are many fish, as kymmie noted with her discus, that use them for shelter; my cardinals and rummy nose do the same, they are almost never out under open light except when feeding. And all these fish will always be more colourful in darker rather than brighter surroundings. You will want some open surface if you have hatchets, so the less light necessary the better.
Thanks for the help, I will continue my search for a tank and research more about below water. I will write back with more information soon.
Okay, so I contacted Oliver Lucanus and he said at the moment he has no rams, but also he cannot sell retail in Quebec and his minimum orders are of 200$ I am assuming his business is a LFS supplier. I am not able to get fish from him, but maybe I can ask where his fish are retailed near me.
Quarantining new fish is always a good idea anyway, so you may as well use the quarantine period to slowly adjust the fish to the water parameters in which you'll be keeping them.
