A scud is a herbivore because it only eats plants. If algae-eating scuds get too hungry, yes, they will eat some plants. We originally collected scuds in the late 1990s from Coleto Creek in south Texas near where Goliad Farms™ is now. What does plants eat from the ocean? The scuds cleaned off algae from Lobelia Cardinals “Dwarf” without harming the leaves. I bought live plants that had scuds aka Gammarus that came in the bag. Scuds are detrivores (scavengers) that graze on decaying plants, algae, fungus, animals, etc. The filter is the small sized sponge filter running with air and I got two of the small stones to keep the water clear. No scuds don't need light. I've had success controlling staghorn algae with Seachem's Excel, but I'd rather not have to use such chemicals all of the time. Scuds are detrivores (scavengers) that graze on decaying plants, algae, fungus, animals, etc. I bought live plants that had scuds aka Gammarus that came in the bag. Apparently, both seahorses and newts (actually, the aquatic larval newts) love scuds. Different species of scuds occur in different aquatic habitats, even deep water, but they are most often found near the bottom substrate, foraging among decaying plants and algae. Member. On the other hand, scuds are almost impossible to get rid of once established. I haven't tested higher amounts so they may be able to tolerate more. Aquaponics and hydroponics growers both use scuds to keep their sumps clean. When we moved to Texas in the early part of this century (2000-2001), we brought along those scuds. Even adult guppies can eat scuds. The scuds had no problem eating the algae off of wood. I was curious about this because these leaves are sofware than those of the Anubias in the above photos.

Short term they can be kept together very well, the scuds tolerate more extreme ph fluctuation and temperature variance and are more prolific for this reason and will likely outperform the shrimp breeding, so they will crowd the shrimp out eventually. Scuds help keep water healthy for other. I have it in my tanks with cherry shrimp, another tank with guppies and another tank with mosquito fish. My first bit of news is that while scuds will eat BBA, they don't seem to be good at seeking it out. This will keep your aquatic ecosystem from getting overwhelmed by the changes new plants cause. When I have had only scuds and shrimp in a tank I get few to no baby shrimp. We live six miles from Coleto Creek, but I never got around to collecting them again. Never seen them eat plants. A few weeks later, scuds began showing up in vats throughout the greenhouse. Either way, they taste really good with a nice white wine.

(meaning unknown species in the genus Hyalella). We hadn’t counted on the myriad species of dragonflies and the voracious appetites of their nymphs. If scud are added to a tank with fish, I think it is likely that the fish will eventually decimate the population unless the scuds find their way into the filter and begin reproducing there or any other place a fish literally can not swim into. To feed the scuds, simply remove 1/2 liter of water from the scud culture (pour it through a net to save the scuds), and put 1/2 liter of the food suspension into the scud culture. Required fields are marked *. Nevertheless, it is wise to maintain a replicate culture in case of a disaster. If so, what kind? So great job and thanks for writing about scuds Mario! Thread Starter; I have some Java Moss and other plants to experiment with and elsewhere I have read they will eat Duckweed but that plant can most certainly take over if given a chance and if they control it and Algae and leave other plants alone, sounds like a win win situation. The only tank of mine that has scuds and fish long term is a no tech 1 gallon fish vase with gravel capped soil that is fully planted and has been up for less than a year with only endler fish: I believe the endlers were unable to eat the largest of the scuds which have reproduced and the endlers are eating the young before they can then reproduce.

Scuds are shrimp-like crustaceans or amphipods. Scud culture by hobbyists can be almost as easy as what we do. Will the fish keep the scud numbers in check? I used to have them in a 5G tank before a greedy Betta fish ate them all, and I ran a small HOB filter on that tank. At the hatchery, I dumped Dr. Gabor’s scuds Gammarus into a 55-gallon vat, added some hornwort (Ceratophyllum demersum), a nice, rootless, floating plant, and forgot about them.
