Need help, with my fish and tanks

  • We are currently upgrading MFK. thanks! -neo
Need to check the nitrate and nitrite. When cleaning that much water which is ok you need to remember your removing considerable amount which will impact water chemistry. I would check your water at the tap and compare it to your water in the tank. Are you puttin in water remotely close to the same temperature of the tank as well as that can shock your fish as well.

I just went to petco and they tested everything and everything is perfect on both tank. I'm probably going to put one by one in the hospital tank until they get better because they are very stress, oh and I forgot my big tank there's white worms and I told the Petco lady and she told me to get a killer worm, i forgot what's it called, but she told me that it works. That the worms are probably stressing my big fish. But I'm going to put my little one in the hospital tank first because he is very stress he's already on his side because he keeps going crazy in the tank going up and down side to side hitting himself.
 
hello; There is a way large WC can be stressful. Has to do with pH change. There have been some posts about this on the forum lately. Some of it has to do with source water parameters and another aspect is how much time between a WC.
A simple way to describe it is if enough time passes between a WC then the tank pH can move. A large WC with source water of a different pH can be a source of the stress.

Might be better to do smaller WC ore often. Say a 25% WC two or three times a week in place of one 50+% each week.

Have you gotten the water quality report from the water company? Don't know about Nova Scotia but here in TN (USA) the tap water company prints a report each year.

I usely take 25% every week but this time I took a little bit more because my big tank he had white worms and usually he doesn't let me clean the tank because he's always attacking my hand. But hopefully when I put them one by one in the hospital tank hopefully they get better and I'll be able to put them back in the big tank.
 
my big tank there's white worms
hello; I do not recall is the worms have already been discussed in this thread. If the white worms are in the substrate and not in or on the fish, they may be what are called "detritus worms". If so a pretty good sign of overfeeding and/or fish that are very messy eaters.
Simple fix is to cut down on the feeding. One lighter feeding a day and two fasting days a week.
Also figure a way to do a vac of the substrate to get the detritus/mulm out of the substrate. Might also consider some snails.
Don't know what a "killer worm" might be.

One more bit of advice. Stuff you are told by employees at a fish shop can be very hit or miss, maybe mostly miss. Might be best to double or triple check any advice you happen to get. I have overheard so many, many wrong bits of advice by fish shop workers. You may be lucky and have a rare good one, but check their stuff out.

I don't overfeed my fish they survived over his poop. My flowerhorn are very aggressive when i try cleaning their tanks, they always trying to attack my hand, so it's very hard to clean the bottom of the tank. But I definitely going to try not to take over 25% and take 25% every week. But I'm probably putting them in the hospital tank until they get better. I have bought clean water from the store. And from now on I will be buying big bucket and when I change the water I'm going to put water in their first in the chemical and let it sit there for a little bit and then I'll add it to the tank.

I just brought the white worms up in the forum a few weeks ago. And the reduced feeding is correct as well as stirring up the substrate before vacuuming to get some of them floating in the water column, shutting off filter and vac then out that way or using a power head with a water bottle filled with floss will also work removing the bottle and replacing th floss every 3 hours. I really would focus on water chemistry and temperature. Adding a new volume of 50% can change your chemistry greatly depending on what’s goin on in your system this is why I said check the tap water before conditioning it and then check your tank water as it stands. There could be a fluctuation your not seeing in the 25% change that has happened with the 50% change. I wouldn’t remove them from their tanks as that could add to their stress.

This has happened before and the way I dealt with it was moving them to the hospital tank and they got better. I'm just trying to prevent from this happening again so I was wondering if this ever happened to anybody. But i always make sure my fish eats everything. But i noticed sometimes that their poop comes out exactly like pellets and it sinks at the bottom of the tank. But I'll definitely will check my tap water because I usually drink for my tap water as well. I'm just trying to get my fish back how they were before because they are very stressed and I don't want them to get worse because my little one he's always getting stress for anything. anything that bothers him he gets stress and then it's hard for him to get back to his normal ways.
 
My 5" flowerhorn is in a bad conditions, i got home and i looked in his tank and he is laying down inside his tank breathing heavy. I don't know what to do, i think he might not survive, the night. My 7" flowerhorn, he still acting the same at the top of the tank, just sitting there. Hopefully he gets better. I haven't seen any changes bad or good ones.
 
Cichlids are messy eaters and heavy wasters.

Anyway to increase aeration in your tank ? The worms are there due to excess food in the substrate and can be an unsightly addition but are apart of clean up crew. I had this issue with my fish and i added a stress coat sup to the tank and blasted my air pump and in a day they all normalized. I had done a large change as well to remove a lot of the worms from my sand and shocked them. I kept the lights off and didn’t feed them for a day.

Hello; First let me suggest that you go back and read thru this thread again slowly. There is some sound advice in the posts. I get the impression some good information may have been skipped. I get that you are concerned about the fish and want them back to normal. However this emotional desire may lead to jumping around too quickly with multiple strategies and skipping some of the more tried and true basics.
First there is nothing wrong with WC of more than 50%. You just need to work up to the larger percentages if you have been doing smaller WC or have been allowing a week or more between WC. While I cannot say for sure what the tank problem is, my guess is poor water conditions. For such a problem larger and more frequent WC is perhaps the best thing to try. Just build up to this by doing a 25% today; 35% the next day or two; 50 to 60 % a couple of days later. Of course WC will not help if the source water is poor.

At the WC time use one of the simple siphon devices which have a small diameter hose with a larger diameter tube ( about an inch and a half) on the business end. Start the siphon and stick the large end into the substrate. The detritus will siphon out but the heavier substrate should not.

One last thing, if you have detritus worms (the white worms in the substrate) then there is too much food in the substrate. By messy eater we usually mean a fish that grinds up it's food. You can usually see little bits of food coming out of the gill covers. I get that you say the fish eat all the food, but the worms are getting nutrition from somewhere. I have had those worms in tanks and I was overfeeding.
 
Yes I didn’t mean to give impression a large change was bad if I did just that if it’s done out of the blue it can be harmful. As with the hobby one of the key words along with patience is routine. And if something isn’t routine it has to slowly be introduced in growin increments.

How are they doing today ?

Anyone think a larger pocket of decomposing food and waste was disturbed and released into the column causing a spike since a larger volume of water was removed ?
