Hi, i curently have a 90 gallon aquarium and my qustion is why my tank keep getting cloudy. I just changed the water yesterday about 30-40 percent of it and now it is cloudy again when i got home from school. could it be my filters, i have 2 topfine filters. will any type of medication work or should i wait to see if it clears up in a few day
I have this fish in it right know
1 common pleco
1 oranite bichir
1 senegal bichir
1 black knife ghost fish
1 angle fish
1 red belly pacu
2 lima shovel nose catfish
2 freshwater barracuda
2 silver tip sharks
most are under 3 1/2in. only the pacu, barracudas shovels noses and black knife and i think the pleco are about 4-5in. if it is over stock which i think it will be soon should i get ride of any of them

welcome to fishlore!!!

What are the readings for ammonia, nitrites, and nitrates? what test kit do you use? sounds like a bacteria bloom ....

i dont have any money to buy the test at this time but i might be able to get it in a week or so. i never had this problem for it with my 55 gallon it hardly ever got cloudy i changed water every two week. if it is a bacteria bloom would any medecation work, i do have NO MORE ALGAE liquid. Also how much does the test kit cost. could it be that it is getting to much sunlight since it by a window. i do have a back round for to block sun light . i do have a small lunar light nocturnal blue could that cause the problem.

yeah.....you're definitely overstocked...here are some links and info i can give you

1. the black ghost knifefish gets up to 20 inches long and needs an extremely large tank

2. the common pleco is fine in a 75, but not with all of those fish, they also get pretty huge
http://www.fishlore.com/Profiles-Pleco.htm
3. your red bellied pacu is definitely too large, i think they need somewhere in the range of a 250 gallon tank!
http://www.aquahobby.com/gallery/e_pacu2.php
4. the ornate bichir is going to need a 100 gallon tank as well, and gets up to around 20 inches
http://www.aquahobby.com/gallery/e_bichir.php
5. senegal bichir, again very large, and will need a bigger tank than the ornate bichir
http://www.aquahobby.com/gallery/e_senegalus.php
6. the silver tipped sharks are actually a brackish fish and can't be kept with the tropicals that you have, they will need their own tank and also get very large
http://animal-world.com/encyclo/fres...h/sharkcat.php
7. freshwater barracuda.....well unfortunately they are probably going to try to eat everything else
http://www.aquariacentral.com/fishin...arracuda.shtml
8. for the shovelnose catfish, they'll need up to 150 gallon tank
http://www.cjexotics.com/yabbse/index.php?page=9
9. is the angle fish you're talking about an angel fish or an angler?
10. also....in your aquarium info it says you have a hujuta gar? i can't find the specific type in a search, but lots of gars can get to about five feet......

all that being said....yes you're extremely overstocked, and also a lot of these fish really can't be kept together, even if you had a big enough tank.

to answer your question, even though they are small now, they are still producing a lot of waste. your tank/filter probably can't handle that amount of bioload. also, you said you have topfin filters? i really doubt that you're getting enough filtration with those....for a 90 gallon i'd definitely recommend a canister filter. i have a topfin on a very small 10 gallon, and it does the job for that but i doubt that it's giving you enough GPH (gallons per hour) on your 90.

whenever something goes array in a tank, testing the water is always a first step to rule out a mini cycle...once that has been done, it could go from overfeeding, to sunlight to just about alot of different things....I know the tank has been running for awile so it might just be the sun as you say..but having a test kit will let you know for sure as well as making sure the fish are always safe and not having to rely on fish stores to tell you good or bad on the water...an API liquid master test kit is the best..it has everything you need and lasts for a long time..you can get them anywhere from $17 up to $40 depending on where you purchase your fish supplies...alot of stores will match online prices also...

Thanks for the info and greeting. ya i figerd it was over stock and i will get ride of some but i want to keep my bichirs since they are my favorite type of fish so could it be possibile to keep them in thier also it is a angle fish. What type of fish can i keep in thier that would be fine. i thought that the bichirs would be fine in a 90 since i have look on google about the fish. Also would they be fine if i keep my freshwater barracuda with the bichir and the angle and pleco.

agabr123

i definitely wouldn't keep the barracuda, he'll probably eat everything else in the tank.

as far as compatibility, i'm not sure if the two bichirs would be okay together, but IMO you only have room for one of them, not both. i don't really know if you could keep the pleco with a bichir in terms of bioload in that tank, and i can't seem to find any info on the angle fish .

xoranitx

Okey, the two bichirs never bother each other, the oranite like to loaf on the bottom and the senegal likes the top. the pleco likes hiding behide the cave that i made so i never seem it, sometimes at night i do. the barracudas dont mess with them either and they wont eat feeders witch i dont like feeding to my fish. They eat flaks and cut up silver sides. Is there any websits that can help me to chose fish that i can keep in a 90gallon and what would be the best filter for my tank and what would be the price range for it

agabr123

IMO the best filter would be a canister filter, they can be priced anwhere from $150 to $300 i think but are definitely worth the money. i'd post a new thread here on stocking for a 90 gallon, there are a lot of very knowledgeable people that will be able to help you i'm not very familiar with bichirs, i don't keep any, but i'm pretty sure that there are members here who do

xoranitx

Alright thanks for all your help and ill post a new thread later and i have to save up for the filter and get it asap

agabr123

no problem, happy to help
