Guppies And Corydoras

Hey everyone!

Just a quick intro about my fish keeping. I've been keeping coldwater fish from the age of 12, and had 2 Fancy Goldfish for 11 years in an 80 gallon. They grew to the length of my hand! And lived a happy long life together. Collin (a silver oranda) sadly passed away eventually from his swim bladder condition and Kariba (gold fantail) became extremely depressed once Collin had gone, and passed away one morning about a month after Collin. Water parameters were fine, she had no visible problems and was eating well. We presumed she was no longer happy without her buddy Collin and it was very sad to see her depressed.

So, it's been 3 years since I sold my last aquarium and I'm slowly getting back into it. This time I wanted a small tropical tank as I'm no longer a kid and don't have time for alla that! Lol. So I purchased a 15 gallon Aquael aquarium, and went through the cycle properly. Water tested almost daily and everything was spot on! Eventually, I purchased my first 6 male all-white Guppies; who can I add are so hilarious and naughty! 1 of them was so small and kinda deformed so I've named him 'Runt' After 2 weeks I added 4 more. They are all babies and really kinda small. They are absolutley thriving and even jump around my hand when I put my hands in to clean or feed. They are fed mainly on Guppy flake, algae wafers, shrimp bug bites and bloodworms! Yuk! They also get a 30% water change twice a week.

1 week ago I purchased 4 baby SterbaI Corydora from Maidenhead Aquatics. From the get go I noticed 1 was runtish looking and sadly passed away after 2 days. I then noticed 1 of them flashing frequently so I started the whole tank on a course of API Pimafix and it seems to be working. Also when I first brought the Corys home, they were severely malnurished. They were all kinda pale and had no food in their little tummies! And for the first 3 days they didn't understand feeding at all. The guppies were taking all the food (and becoming fat) and I was getting so worried they were starving . However, since they've been on Pimafix treatment and realise the Guppies aren't going to kill them... They are foraging all day and eat when I feed them! Phew! Now within just 1 week they have pop bellies and are full in colour.

I am going to stick with this aquarium for a while and in a few months once we relocate to a different apartment, I'm looking to buy a 30 gallon aquarium and buy 4 more Corys, I know they must feel a lil lonely.

Does anyone else have Guppies and Corys?

 

Welcome to Fishlore

I have guppies & cories as well! Unfortunately I had nearly 50 guppies (including fry) but due to fish tb, I only have three survivors

I have 9 albino cories in my 32 gallon. They are funny little things!
Good call on your cories by the way. They appreciate the larger footprint.

 

HI & welcome! I don't have any guppies but I do have cories and love them. So cute and fun to watch. I'm with you on the yuck factor of blood worms , but my little crew loves them so much I put up with how gross the blood worms are.

 

I have a YouTube channel on my aquarium if anyone wants to take a look!

My account is - Guppy Love
Or type in - White Moscow Male Guppies and my videos should show up! Let me know your thoughts.

 

Watched your video, what a unique & pretty aquarium! Very nice job!

Thank you so much Cherie G!

Hey guys,

So 1 of my Corys is looking significantly lighter than the other 2. He/she is also smaller.

I fed them bloodworms last night and they all ate well. Does anyone know what it could be?

 

Is this a loss of color or has it always been this color?

Are water parameters okay?

It has always been lighter than the other 2 but seems to be getting lighter almost to the colour of the sand. I am currently moving apartment and have packed away my test kit, and won't be able to use it for at least a few days. I could take a water sample into store?

 

Color loss is normally due to a few factors:

1) Stress on new fish (but you've had them a week)
2) Water quality
3) Sickness

Since you mentioned flashing and treatment getting better I'm not sure what might be wrong. It wouldn't hurt to check the water quality to be sure. Then you could at least rule that out.

I change the water at least twice a week usually, however as I'm going through treatment I have to wait 7 days for it to take full effect and can't do a water change. It's making me think sickness, as the other 2 are fuller in colour and are slightly more active. The flashing has stopped completely now and they are eating well.

I'll take a water sample to the store! Hopefully the Pimafix won't effect it.

Thanks!

 

The pale Cory sadly didn't make it. My nitrites were quite high because I've been unable to change water as treatment was taking place. Did a 50% water change yesterday and the remaining 2 Corys are doing really well.

I have 10 Guppies and now 2 Corys in the aquarium. Am I able to add more Corys? I'm worried the Corys are lonely. The aquarium is 2ft long by 1ft by 1ft (roughly 60L)

 

Best thing is stabilize everything first then add more cories later.

If you have a 60L tank why would you be changing 30,50% twice a week?

To keep ammonia levels down as it is still a new aquarium (6 weeks old). I was advised to do this for a while until the aquarium matures, also with Corys being so sensitive to poor water quality. Is this too much?

 

Oh your initial post indicates as if you went through the cycle.

Do you have any indication from your previous testing how much ammonia and nitrites go up per day? You might need more frequent less volume water changes but we'd need to know the numbers. Corys are quite sensitive.

I peg my fish in tanks for 1ppm ammonia max and .125 ppm nitrites max during fish in cycling. Also, tank temperature and PH level have an effect to how toxic these levels are or aren't. On our newest 10G I have to do daily 25% water changes to maintain everything with fish in. The ammonia level goes up .25 ppm per day in this tank with nitrites just barely detectable with a load of 5 guppies and 6 green corys.

It had but upon taking a water sample into store they suggested 2 good water changes per week? And I was previously doing 2 30% WC per week because I know how quickly ammonia can creep up. I'm not sure on how much my ammonia and nitrites go up per day, but I do recon my nitrite levels have sky rocketed because since getting the Corys I have been overfeeding to make sure they're eating. Now they are all in a good routine and the Corys know when it's feeding time so I'm back to 1 feed per day. My temp is 23° currently. 1 Cory is very dark and colourful (called Derek) and Dotty is a lot more dull in colour. Dotty has become extremely active today racing around the glass and almost bumping Derek? Derek is very active also but more chilled just foraging all day in plants and rocks. Ahhhhh! Might just grab a test kit myself from the store whilst I'm moving. Thanks for your suggestions!

 

I've uploaded a video

Anyone know what Dotty's doing? She's obviously a lot paler than Derek so I'm getting worried now. Any suggestions will be appreciated!

 

In order to know how frequently and how much water you need to change you need to know how much your ammonia, nitrites and nitrates go up over time especially, if you are having problems.

 

I think your current water change schedule is good.
