Is Seachem Paraguard Safe For Shrimp?

An in-water broad-spectrum drug called ParaGuard(tm) may stress plants and invertebrates (corals, mushrooms, shrimp, crabs, etc.). For this reason, it shouldn’t be used in tanks with plants or invertebrates.


Looks to me like stress. The adult shrimp are the ones most harmed by stress. Babies can also die from bacteria.

Perhaps the best course of action is to do nothing. Add new water slowly while performing one more 20% WC, then observe the tank for a few days. You are on the correct track if there are no dead shrimp and an improved shell color.

If you have bacteria, it’s probably already too late to save shrimp with a weak immune system.

Should you nonetheless choose to employ it. Take 25% for one day, 50% for two days, and then 80-100% of the recommended dosage.


What varieties of shrimp and fish do you have? You could go natural and raise the temperature to 86 degrees for two weeks if your fish prefer warmer temperatures. If your fish prefer cooler temperatures, don’t do this.

Seachem Paraguard is a different approach. Shrimp, snails, and plants are entirely safe. In the past, I’ve used it to cure fungal and Ich problems in my heavily planted tanks.

Possess you a quarantine? In the interim, shrimp and snails should be alright in another tank because they don’t acquire ich. The main challenge is getting them out. Good fortune


When I looked into Paraguard before using it, it appeared that individuals on shrimp forums were claiming this. I have used it myself in the past with no negative affects on Amano shrimp. I wish you luck.

There have been instances where people successfully used it with invertebrates, but there have also been issues. We urge care if you do decide to use it; dosage at 1/4 to 1/2 dose and monitor how your invertebrates and soft corals respond.

A live bacteria-containing biological filter addition that enhances the biological filter’s development and aids in cleaning a dirty aquarium. The growth of nitrifying bacteria is hampered by the accumulation of organic pollution in the aquarium. By devouring dangerous organic pollutants, the bacteria maintain ideal circumstances in the aquarium for the development of the biological filter. This hastens the biological filter’s development in newly constructed aquariums.

In the aquarium, an accumulation of organic substances also encourages the growth of pathogenic organisms. maintains the biological filter’s optimum operation by maintaining the cleanliness of the filter and aquarium gravel. When used frequently, both the living environment and the quality of the water are improved.

Which water type is ideal for shrimp?

When compared to Neocardinia, these unusual shrimp are often more expensive to buy and require more careful tank maintenance. These Neocardinia cousins require a bit more maintenance, but you are rewarded with stunning displays of color. Thanks to years of selective breeding, Cardinia Contonensis has seen several stunning color variants.

You may develop a thriving population of Cardinia Contonensis shrimp with careful planning. Cardinia Contensis has distinctive hues and comes in a variety of patterns, including spots (Black Pinto), stripes (Black King Kong), and solid colors (Extreme Wine Red). Anything is feasible in terms of color, from pure black to the traditional red and white crystal red.

Most of the Caridina species we see in the hobby are Crystal/Bee shrimp, Tiger shrimp, and all of their combinations. The patterns and markings of shrimp are described by the phrases “crystal,” “bee,” and “tiger.” To further define the precise appearance of the shrimp, there are numerous distinct gradings and color morphs within each of these pattern groups. The Crystal Red Shrimp is arguably the most well-known Caridina species (other than the Amano). They provide the tank they are in a splash of red, similar to cherry shrimp. Crystal Blacks, Blue Bolts, Black King Kongs, and Tangerine Tigers are further common Caridina shrimp.

Water parameters outside of their optimal range tend to be less tolerable for caridina species. Most of them like to be kept at lower temperatures, often in the upper 60s to low 70s, and struggle in temperatures higher than 76F. They favor acidic or neutral soft water. They will reproduce most successfully in environments with a pH of 6.8–7.5, GH of 4–6, and lower KH. Although they can survive in slightly harder and more basic water, it has been noted that they do not flourish as much there. These shrimp can grow up to 1.25 inches in length and have a lifespan of 1-2 years.

  • Recall that these are merely typical water characteristics that pertain to the more widespread varieties of shrimp in each species. They do not apply for every single species. Please do your homework to determine the ideal water conditions for the particular shrimp you intend to maintain.

Does ICH support ParaGuard?

The only aldehyde-based (10% by weight) parasite control product that is safe for fish and filters is called ParaGuardTM (for parasites on fish). Contrary to highly poisonous and challenging to use formalin-based drugs, ParaGuardTM doesn’t include formaldehyde or methanol and won’t change pH. Many ectoparasites (such as ich, etc.) and external fungal, bacterial, and viral lesions are effectively and rapidly eliminated by the use of the proprietary, synergistic combination of aldehydes, malachite green, and fish protective polymers known as ParaGuardTM (e.g., fin rot). When adding additional fish to a community tank or hospital tank for sick or injured fish, it is especially helpful.
