Hello All,

I just started my tank 2 nights ago. Last night I added Fish. I did not learn about cycling until just now. The staff at petco simply told me to wait 24 hours and put fish in.

Here are the tank stats

Amonia .5ppm
nitrate 0ppm
nitrite 0ppm
pH 7.1

I have 12 fish in this 55 gallon tank. I have 5 gouramis, 3 catfish, 3 shark, and one algae eater. They are all small/young. They seem to all be very healthy and alive.

I just did a 10-15% water change to aide in the cycle of the new tank.

What levels should my nitrate and nitrite be? I need a cliffs notes aproach to this if at all possible. I have been using water conditioner as well. I just want to know what i need to do to ensure the vitality of this new tank. I am very excitied to see them grow.

Thanks for helping me out.

The cycle hasn't started yet. That's why there are no nitirtes. You'll need to do 50% water changes DAILY to keep all of the levels down. What types of catfish & sharks? And algae eater. Chances are all of these will outgrow a 55 gallon tank. And most sharks cannot be kept with others of the same species-besides balas. And balas get HUGE. Is the algae eater a pleco? A common pleco can reach 2 feet! Much too large for a 55 gal.

Do large water changes every day and use Prime water conditioner during water changes. This seems the recommended advice of most here when people end up doing a cycle with fish.

Ideally nitrite should be 0, ammonia should be 0 and you should show nitrate levels

If possible maybe try returning the fish.

with this many fish in such a small tank you will have nitrate problems you have over stocked and putting a algae eater in a new tank is not good as it will not have food for a while unless it eats wot you are feeding your fish ,
with so many fish when your tank cycles you run the risk ov killing a few as your tank cant hold the load so i would rehome or return some of the fish to store indefinate and ask if they can hold the ones you wont then dose tank and check that tank has cycled
then put your stock back in

it is a pleco. It is about 6 inches right now. But how can all of these fish get so big in a 55 gallon? wont they grow to accomoadate the tank and surroundings? I forgot the names of the sharks but I will describe them.

The sharks have red fins and grey bodies. They move very sporadically.

The catfish are acutually sharks I think. They are very svelt shiney and wag their bodies. They have whisekers but the rest of the body looks like a shark.

So are you saying a pleco cannot be put in a tank of 55 gallons? Are these fish only for super sized aquariums? I don't quite understand.

Amanda

NO, that is the biggest fish keep myth! The fish will keep growing until they no longer can. Large fish kept in small tanks will usually die - or have a shorter life. Those are Red Fin Black Sharks - Only ONE can be kept in a tank! They get VERY aggressive towards eachother as adults. A COMMON pleco cannot be kept in a 55 gal. They're best in 100 gal. +

Freshwater Fan

wow- i am very upset right now, petco really did not tell me the right thing to do. Now I am may harm the fish.I am going to hope for the best. So, I will do 40-50% water changes, ( will not be vacuuming the gravel though) DAILY for the next week or so, Am I correct?

Amanda

Those sound like Colombian Black Fins. They get HUGE. Need a 100 gal + tank also. They also need salt in their tank - they are a brackish fish.

Everyday. You will first see an ammonia spike - then a nitrIte spike. Both are LETHAL to the fish. Then there will be a nitrAte spike. Keep doing 50% water changes until all of this happens and the ammonia & nitrite are 0. The nitrate should be 10-20. It is probably best to return all of the fish. There's a good chance that none of them will survive the cycle & most of them cannot live in a 55 gallon tank. The RFBS will kill each other when they get older. And the columbian sharks reach 14+ inches! Not to mention the pleco that will reach 2 feet.

Welcome to FishLore!

There are several types of pleco, and each type has its own average adult size. So plecos in general are not just for super-sized aquariums, but common plecos sure are... that is one big fish.

The main concern with overstocking is not that the fish's body is too big for the tank (though that also is a factor). The most important deciding factor on tank stocking is how much waste each fish will produce at its average maximum adult size -- you must always plan for when they're grown! For instance, an average goldfish needs 20 gallons of water to itself, and then 10 more gallons of water for each goldfish after that. It seems preposterous, as most goldfish don't get gargantuan... 30 gallons for 2 fish? But when you look at what an incredible amount of waste they produce (they're notorious poopers!)... you see why you need all that water. Fish waste contaminates your tank water with ammonia, which of course is highly toxic to fish. The less water and the more waste, the faster the ammonia builds up... and kills your fish. So it's very important to be sure that the tank can handle the waste -- or bio-load -- that your fish are producing.

okay- so what are the best fish to keep in a 55 gallon tank?

welcome to fishlore..as most have said, its the cycle thats very important at this stage...you maybe overstocked but getting the tank cycled is first priority...if you can get some conditioner called prime, it locks down the ammonia for 24 hours until your next water change..which as most have said, should be daily 50% ..the prime goes right in the tap water that you put into your tank...I think your catfish are pictus catfish and are cook critters and fun to watch...all the fish you have are very senisitive fish and will need the prime and daily water changes to survive...goodluck and patience is going to be your best friend at this point..it could take weeks to cycle with fish

Amanda

The gouramis are fine. Although I would only have 2 - they are VERy territorial. Depending on the species, they can get pretty big too. Tetras do very well in 55 gal. As well as cichlids. I have an african cichlid tank that is 55 gal. But A LOT of research has to be done before anyone buys fish. The best thing to do is go to the store, write down the types that interest you, and let us know here. There are many people that can give you some ideas & let you know what works & what doesn't.

Freshwater Fan

Thank you all for yur responses. What I will do is dfo the 50% water change daily for 2 weeks, get the prime conditioner tonight. How long would it take for the pleco and sharks to grow to be too big for the tank? I may want to keep them to avoid the hassle of bringing them back to the store and fighting with them them that they did not set me up correctly. I definitely should have researched bere getting an Aquairum started. Well, lets try to make the best of what we have at the moment.

Amanda

Do you have any local fish stores - not chain stores - in your area? They usually will buy fish for cash or store credit. You're also better off going to a non-chain store as they USUSALLY (not always) give better advice & have healthier fish. The longer you keep them, the more attached you'll get. Plecos give off a large bio-load. What type of filter do you have? It may be a good idea to over-filter your tank b/c of the overstocking issue.

Freshwater Fan

So what WASSupposed to do that I did not? How do i cycle without fish? Doesnt there need to be a build up needed from the fish themselves? How would the water prime itself withut the fish?

Amanda

No, you can add straight ammonia to do a fishless cycle. Then you keep tabs on the nitrite & nitrate levels.

If you are going to return any, do it soon as they only allow returns for so long usually...the growout rate for a common pleco isnt that fast but his waste is still constant..a bala, if thats what it is, grows a bit faster ..be prepared as it could take longer to cycle..one never knows.took me 9 weeks with fish in my 75 gal ..but you are well on your way with alot of help...
