My 48 Litre Tropical Tank Diary

Your tank is only 10 gallons and far too overstocked. . If the guy in the fish store is telling you this stocking is ok for a 10 gallon I can promise you he's wrong. He's also given you bad information on cycling a tank. It takes around 4-6 weeks to cycle a tank, not a week and a half. Adding mature gravel will NOT mature your tank anywhere near enough to be able to dump a load of fish in the way you have. The only way you can instant cycle a tank is by filling the empty new filter with mature sponges, from another filter that's been running for several months.

Adding stuff from bottles, products such as Cycle and so on DO NOT WORK. The reason is because to stay alive, filter bacteria need a good flow of water over them, and fish waste or ammonia to feed them. Without these things, the bacteria start to die after around a day. Since these products you've been adding have been sitting on a shelf in a shop for weeks, and been in storage for weeks or even months before that , any bacteria they claim to contain will be long dead. You're basically wasting your money on a bottle of empty liquid.

Since you did not cycle your tank correctly, your tank is now going through a fish-in cycle. Your fish are being exposed to high levels of ammonia caused by their waste. Your filter will not yet have enough bacteria to process that waste, so it's builing up in your water. This is the most probable reason your fish got whitespot.

You didn't bother to do your research and now they have to suffer for it.

You cannot fit any more fish in your tank. You need to remove half of them in order for the rest to live properly and have space. Walking into a fish shop and buying a load of fish, without even bothering to think about wether your setup is correct or can cope with the extra waste is a very poor attitude to have. These are living things not just something pretty and exciting to look at. A tank is an enclosed environment, where waste and other such things have nowhere to go but through ythe system you set up. If you don't set it up correctly, you're going to cause them to suffer, and they have nowhere to escape to. In owning them you have a duty to give them correct care and you haven't done this so far. Admittedly you have been given some very bad advice by this guy in the shop, but this doesn't excuse you from doing your own research.



According to your signature your current stocking is now as follows :

1 Female Golden Mollie
3 Male Fancy Guppies
1 Red Wag Platy
1 Male Rosey Barb
1 Female Rosy Barb
8 Neon Tetras


This is too many fish for your size tank. They may be babies or small at the moment, but they will grow and when adults, they will have even less space to swim than they do now despite all being relatively small species.

It would be kinder to your fish to re-home or return some of them. A more manageable stocking for your tank would be any of the following:

8 neon tetras and the red wag platy

OR

The pair of barbs and the 3 guppies

I'd forget the molly altogether and return it as they tend to be healthier in brackish ( slightly salty ) water.

You should never had added the betta at all.

Do NOT remove the heater and add a goldfish if these current fish die . Goldfish require 55 gallons+ per pair of fancies or 40+ gallons per single comet or normal bodied goldfish.


You also need to do small frequent water changes to help bring the ammonia down and give the bacteria time to grow. There is a thread on Cycling on this site. Read it.

You also need a liquid test kit so you can measure the ammonia , Nirtrites and Nitrates in your tankwater ( do this before water changes, not after ) to check that your filter is cycling properly. You won't be able to tell if the filter is cycled just by looking at it, and strip style tests are very inaccurate. API do a good liquid test kit.

After the filter is cycled, you can drop the water changes to 25-50% once a week, every week.
