Q. I bought my son some sea monkeys about eight months ago and they are still living. At first we had around six and the number has varied from a low of two up to a high of around thirty. We often see new baby sea monkeys swimming around but very few live to maturity. Are we doing something wrong or is this normal? If you notice a new batch of little ones, should we be feeding them more? I’m looking for some tips to help more grow up. A. Unfortunately, I have noticed the same thing in my tank. The little ones show up, then disappear, never seeming to reach adulthood! Try not to feed them too much, that is a common problem, and add more oxygen to their environment. You can do one of two things:
1. You can blow air into the tank with a straw – like you do with milk – and this should help them out. I know that you are blowing CO2 into the tank but there is some oxygen in there too; or
2. You can move the Monkey water from the tank into a jar, back and forth a few times, to help aerate the water.
This will help them a great deal because they require a lot of oxygen as they are growing up. Try to do these things on a regular basis – a couple of times a week – to help the little Monkeys grow.
Q: Why is there greenish things on the bottom of my sea monkey tank? Is it fungus, sea monkey waste or what? My sea monkeys keep on diving into it. A: It’s a photosynthetic algae. It’s not a bad idea to remove some if it gets out of control, but *don’t* remove all of it! Not only do the Sea Monkeys eat it (salad?), but it also helps to oxygenate the water! (You may wish to include some vinegar for that salad….don’t do this, I am just kidding!)
Q. Can I put a neat little aquarium castle in the ocean zoo so my Sea-Monkeys have a place to play? A. Yes…..that’s a lovely idea and it will give them something to do. Their lives are awfully shallow and they really need something to do with their free time. They get tired watching you have fun and, as they can’t get out and go for a walk like we do, they might really enjoy a little castle. In addition, they may wish to hide from each other during games of hide and seek or when they are having a fight. Sea-Monkeys can be vicious little buggers and I’m sure that the weaker Monkeys may appreciate somewhere to hide.
Q. Since Sea Monkeys need oxygen, is it OK to run a small fish tank aerator all day, or for a few hours a day? Do you know of anyone who has used such a setup (including a small filter)? A. Actually, there is a product that you can get that is a little tube with an air filter on the bottom called the Million Bubble Air Pump (picture a straw with a large blue fish tank filter on the bottom – strange but true). They suggest you aerate the tank once per day. Mine have done fine without it. I would suggest that you just blow into the tank with a straw – it really works. They do need oxygen to think and live. I don’t suggest that you use an aerator as a friend tried it and killed them all. The algae went nuts, proliferating out of control, and the Sea Monkeys all died!
Q. Could one use any size tank for those darn little critters or should one only use the 12 oz. size? A. You can put them in a bigger tank but it is recommended that you get the larger size of Water Purifier and Jumbo Living Plasma for them. This will ensure that they will flourish in great numbers!
Q. I have tried to keep Sea Monkeys twice but they always die in a couple of days. I keep them in a plastic clear container. I feed them correctly but still they die. I was going to get another pack but my mom said to forget about it cuz’ they would just die again. What can I do to keep them alive? A. You must get air into their tank in the first two weeks and thereafter to make sure that they are going to live. When they first hatch they need a great deal of oxygen to make it through the first couple of days. You must make sure that they have enough water in the tank because the salt in the tank will build up and make it tough for the Sea Monkeys to shed their skins and grow. To add air to the tank you can do one of three things:
1. blow into the tank with a long straw for about 2 minutes per day;
2. move the water back and forth between the tank and a clean container (don’t worry, they won’t get hurt); or
3. use the “Million Bubble” air pump at the bottom of the tank for about 2 minutes.
Don’t feed them in the first week because they have enough food in the hatching kit!
Q. I have a dilemma. I bought a Sea-Monkerys ocean zoo but I noticed that the lid comes of very easily and that it has 2 big holes in it, making it very dificult to transport. I decided to use a cleaned-out peanut-butter jar with a airtight screw-on lid. Then my friend told me the little fellas would die in there because they need lots of oxygen to live. I need help! A. I would suggest that if you wish to use your peanut butter jar do the following:
1. Clean the peanut butter out. Pretty obvious but you would be surprised what people do to Sea Monkeys…..And, they are anaphalactic which could cause quite a nasty reaction to those little ‘nuts!
2. Put some holes in the top of the jar to allow them to get some oxygen!
3. Blow into them regularly to make sure that they ahve enough air.
4. Don’t leave them in the jar too long….only long enough to transport them to their destination
Q. About 6 months ago, I had my own family of Sea Monkeys. They lived for 5 months, then gradually, most of ’em died. *sniff* Just recently, I have ordered some Sea Monkey eggs and the water purifier and the food through the order system in the booklet. But can I use the old home of my other family?? Or will that upset them? Also, I was wondering…I still have 3 Sea Monkeys left from my previous family. Would the new family accept them into their family…or will they be rejected? Please help! A. Yes, you can use their old home, it won’t upset them too much. Just remember that you must remove the old corpses before you put the new Sea Monkeys in. If you have some former Sea Monkeys I would suggest the following to you:
1. Put the old Sea Monkeys in a glass jar – try to go for a 12 oz jar if you can. Don’t put the lid on top of it or, if you do, then just put some holes in the top of the jar!
2. Set up the tank for the new Sea monkeys, following the instructions closely etc.
3. When the new Sea Monkeys are born, wait about a week (or two to be safe) and put the old Sea Monkeys into the tank. The reason for this is such: the new Sea Monkeys need all of the oxygen that they can get and the old Sea Monkeys may use some of that wonderful O2 for their own needs. It helps the new Sea Monkeys to live. When you can just see them – in about one week – you can add the old Sea Monkeys to the mix. Don’t worry, the little Sea Monkeys are so safe it’s not even funny. They are not cannibals and, if you are lucky, the old Sea Monkeys could teach the new ones the ropes a little…
Q. I have a fish tank that is void of fish at the moment and, seeing as how I don’t really like goldfish, would it be okay if I put Sea Monkeys in my fish tank? It has everything they would need and more, but I’m still worried. A. How big is this tank? I would not recommend doing this if the tank is larger than about 24 oz (and that’s pretty small for a fish tank, isn’t it?) The reason for this being that the Sea Monkeys need a concentration of the Sea Monkey plasma, which contains all kinds of great minerals and nutrients for the Sea Monkeys. If you wish, you can order some Plasma from the Transcience Corporation which will help you with a larger tank – I think it is something like one gallon of water will be permeated with this formula.
