It's exciting whenever a fish owner discovers they have newborn fry, whether it was by intent or by accident. However, the real challenge now begins - how to feed the little guys? Conventional foods are not only too large, but often lack the requisite nutrition that fish fry need to grow properly. As a result, many young fry are lost, due to lack of the proper food. It's ideal if you can plan ahead, but even if you can't, this primer on feeding fry will help you get through those critical first few weeks.

While you can often use rocks from the great outdoors, it's important to be aware that anything you put in your aquarium can impact the water chemistry. Unless the rocks come with a tag that says they are aquarium safe, you'd better test them before tossing them in your tank. How do you test rocks? Here are my tips for how to sort out the good rocks from the bad ones.

Whenever I'm asked which fish are particularly hardy, a number of fish come to mind. Quite a few of them are Danio species, and with good reason. Danios usually don't mind cool water, so they are great for unheated tanks. They play well with most other species, will eat virtually anything they are given, and tolerate a wide range of habitats. Some are small enough to be kept in mini tanks, but as a rule, Danios are best kept in schools. In a large tank, a school of Danios can be a stunning display. For those just starting a new aquarium, most Danios make an excellent first fish.

Every aquarium has some phosphate (PO4) in the water, even though you can't see it. Should you be concerned about the amount of phosphate in your aquarium water? And where does it come from in the first place? Will it change over time? Those are all good questions.
Depending on the water source, it's possible to have a fair amount of phosphate from the get go. Once the tank is running, those levels can rise. Everything from uneaten fish food to fish waste to water additives can increase the phosphate levels in your aquarium water. Over time phosphate levels can rise enough to contribute to algae growth. Here is how to avoid phosphates, and reduce them if they get too high.

Often, that's the point at which the discouraged fish owner gives up for good. Before that happens to you, educate yourself. Knowing how to recognize and treat disease will allow you to conquer it before it kills your fish. Better yet, knowing how to prevent Ick will keep you from ever having to do battle with it in the first place.

I often hear from people who lose fish after a relatively short time. Less often, I am blessed with messages from people telling me their fish has lived for many years. Recently I heard from a fish owner who had a Goldfish for 18 years, which actually is expected for that species. Unfortunately, most Goldfish rarely live their expected lifespan of several decades or more, often due to improper care. Thankfully, many owners do a great job of caring for their fish, and some even share stories of their 'senior citizen' fish. How long has your oldest fish lived? 1 year

Known as either the Red Line Barb, or the Denison Barb, this attractive fish is one of the larger members of the Barb family. The brilliant red line that runs through the eye makes them hard to miss, and has made them a big seller in recent years. However, they are not for the average small to medium sized aquarium. They reach an adult size of half a foot, and need to be kept in schools, making them suitable only for large aquariums. Denison Barbs do well in a community aquarium of other large fish, or as dithers in a cichlid tank. Be prepared to pay a bit more for these Barbs, as many of them are still wild caught, even though captive breeding programs have been in place for a few years.

A sure way to start a spirited discussion is to bring up the subject of how to ground your aquarium. I've heard plenty of arguments about the safest, or most cost effective, way to go about grounding the tank. As for me, I don't even engage in that discussion, because I think it shouldn't be necessary to ground it in the first place. If you are getting a shock from your aquarium, something is amiss. Instead of debating the finer points of how to go about grounding your aquarium, how about solving the root cause of aquarium electrical shocks instead. Once that's taken care of, grounding is a moot point.

There is little doubt where this fish came by the name Yo Yo. Named for the Y's and O's adorning its flanks, the lively Yo Yo Loach doesn't come with a string like the toy it is named for, but it's just as much fun. Although undemanding to care for, it's wise to read up on the habitat and feeding needs of this attractive loach before bringing one home.
Barbara Brooks provided this great photo of a young Yo Yo Loach showing its famous markings. If you'd like to submit your own photo to be featured, fill out the submission form and send it in.

Have you wanted to try live plants, but were afraid you'd become a serial plant killer? Never fear, there are some aquarium plants are durable enough to survive even the worst brown thumb. In fact, some are almost impossible to kill off. Dwarf Hygro is an attractive aquarium plant that is fast growing, easy to care for, and almost indestructible. Hailed as the ideal choice for a newly set up aquarium, this plant actually thrives on any excess nutrients in the water. Dwarf Hygro also does well in a variety of water conditions, making it a great choice for those who don't have perfect water.
