Ive kept many of the emerald and red mithrax crabs over the years without incident, except for two that I had to remove. For reasons unknown, one started pulling my hermit crabs out of their shells and eating them. Another started eating some tiny featherduster tube worms. Id never heard of either of these things happening before. Its still a bit of a mystery, but the crabs had been living in the aquariums for at least several months and had cleared out all of the bubble algaemaybe they were just really hungry. Id still add them to an aquarium without worrying but would keep an eye on them and give them some pellet food or other tidbits if they got aggressive.

Mollies, guppies and platies are not the best algae-eating fish, but they will bite off and eat soft hair algae and some strand-like types of algae. Black mollies can be raised solely on an algae diet, eating fuzz algae and beard algae, but they are omnivores, surviving best on fish flakes. Live-bearing fish species can be an option for your freshwater aquarium, but you may want to consider adding another type of algae fish to your tank to help keep your tank clean and free of an algae overgrowth.

As well as being cool to watch, freshwater shrimp can also help with algae control in your home aquarium. While they are little to no use in combating the filmy types of algae, they are effective at getting rid of thread and bush varieties. The only downside is the fact that they are small, and are a preferred food for a lot of freshwater fish, so keeping them in a tank with other fish can be tricky. If shrimp have enough hiding places, they can do fine, but in an open environment, they probably won’t last very long. Here are some of the best algae eating shrimp that are most commonly found in the fishkeeping hobby.

A common worry amongst is algae. Despite the fact that algae occurs all over the place in nature, its presence in our little slice of nature (the aquarium) can be quite troublesome for fish tank masters. While a little algae is to be expected in any environment that features water, light and readily available food (both leftover fish food and biological castoffs) too often can be a problem.The recommended temperature for this fish is around 72-75° Fahrenheit, but they will survive if there are only a few degrees difference. On the other hand, some aquarists claim warmer water will cause it to eat less and increase the algae, so it is better to keep them in tanks with cooler water.
