Generally speaking, larger fish have slower metabolisms than smaller ones. As a rough rule of thumb, larger adult fish can go longer between meals than smaller ones. In fact, adult fish with slower metabolisms like Goldfish really only should be fed a single time per day. Adult Goldfish are some of the easiest fish to overfeed as they will eat constantly regardless of how much they were fed earlier.
Not only does their metabolism slow down as they age but they are also cold water fish. For small fish with faster metabolisms, you can offer a single light feeding every so often for the same results. If you need to leave suddenly for a two-day weekend, your fish will be absolutely fine. Unless they are small fry, which need constant feeding. But what about if you need to be away for more than a few days?
Automatic fish feeders are my tool of choice for this situation. These devices store prepared foods in a hopper and can be programmed to dispense some as often or as little as you wish. I highly recommend having an automatic feeder on hand a few days before your trip so you can work the system out and ensure it operates properly.

What do minnows turn into?

The minnow is often thought to be any small fish, but in fact, they can grow to be as long as 3m and up to lbs. What to feed minnows to keep them alive? A great food choice for minnows in an aquarium is freeze dried blood worms. Another option is to simply feed your minnows tropical fish flakes or even goldfish flake food. Some minnows are pickier than others, choosing not to eat the flake food.
How fast do minnows reproduce? Females release an average of — eggs per spawn, with larger females releasing — eggs. If possible, write down all of the above in case the sitter forgets something. Also, leave contact details so that you can be reached easily in the event of an emergency. Another great alternative if you cannot get a fish sitter is a vacation feeder.
This is a commercially packaged slow-release feeding blocks. Vacation feeders come in a variety of shapes and sizes and are designed to feed your fish for specific periods of time.
The main disadvantage of these is that the food they contain may not be what your fish are used to consuming. To curb this, try exposing your fish to the specific feeding block you intend to use while you are on vacation. Stop feeding them as you normally do and place the feeding block in the aquarium. These are designed to hold and dispense free-dried or dry food items. They come in a wide variety of designs and can be programmed to feed your fish once daily or every few days. They work by rotating a compartmentalized drum or plate via a timer.
You can adjust the amount of food given in each feeding, and it can keep your fish fed for weeks. While the idea of automatically feeding your fish is appealing, it is important to understand that in case the filter stops working, continued dispensing of food will result in a polluted aquarium.
This may ultimately cost your fish their lives. With a little preparation and planning, taking a vacation should not be a life-or-death situation for your fish pets. While many fish can survive a few days without food, the most important thing to remember is that maintain a regular maintenance schedule as well as avoiding overstocking of the aquarium will go a long way in ensuring the health of your fish when you go on vacation.

Are there other options? HTH, Jim. OrionGirl No freelancing! Aug 14, 14, Poconos Real Name Sheila. I agree with Jim and Dave--the only exception are fry. Many fry will die if not fed daily. Oct 29, 0 0 brooklyn, NY Visit site. If the fish are accustomed to being fed multiple times per day, then, although they should be able to go for an extended period without eating, the change will certainly affect them to some degree.
I would think that the best approach would not be to test their endurance, but to leave them with some kind of food- perhaps an automatic feeder like RHJ suggests, or even one of the dissolving food packs. What kind of fish are they? Some species can be very sensitive to such changes, while others fare much better. Where are you going on vacation-somewhere warm i hope Dec 27, 1 0 44 Oklahoma www. I apologize for stealing the post but how old of fry do they need to be fed daily?
I'm going to be on a 3-day trip in early February and we aquired about 30 baby mollies we have in a breeding net in my 55 gallon community tank. I've been trying to cut down on feeding our tanks but when I tried to feed the fry, the other fish smell the food and attack the net trying to get it. Some even wedge themselves inbetween the net and the glass and I have to free them so we've been feeding that tank along with the breeding net.
The fry should be weeks old by the time we leave and I was going to have a relative stop by to feed them once while we were gone but if the fry can make it 3 days, I may just leave them be.
