Peacock Gudgeons are one of the most beautiful and interesting freshwater fish. They come from Papua New Guinea and are a member of the Sleeper Goby group, but unlike most other sleepers, they can be seen swimming throughout the entire aquarium. They are also known as Eyespot Sleeper Gobies because of the black eyespot that can be found on their tail. Their colors appear to change under different light, but their base color is a pale iridescent pink-purple-blue with darker pink, orange, yellow, and black markings.
Sexing this fish is relatively easy, as mature males are usually larger than females and have an obvious cephalic hump along with dorsal and anal fins lined in yellow, while females lack the cephalic hump, and their fins are lined in black. Females also have a rounded belly much like females of P. pulcher, but where P. pulcher is crimson the female T. ocellicauda is yellow. The eyes of the male fish will sometimes reflect red-orange, while the eyes of the female appear black.
They are very peaceful and timid and can be housed comfortably with other peaceful, slow moving fish. They are good candidates for the planted aquarium because they will not eat or uproot plants. They are not aggressive, but males can be territorial, so it is important that each gudgeon has its own cave to defend. After spawning, males will defend the eggs, but once they hatch the male will likely eat them so fry are best reared artificially.
They can be difficult to feed, as they will not usually accept flake, pellet, or freeze dried food. They prefer live foods such as worms and artemia, but can be persuaded to accept frozen food with time. They are slow feeders and should not be housed with fast moving fish, including tetras and danios, because they will likely be unable to compete for food.
I have a Peacock Gudgeon in a small community tank with otos, corydoras, bumblebee gobies, and guppies. The Peacock seems to enjoy or at least tolerate the addition of salt (1/4 tsp per gallon), and is peaceful toward all of its tankmates but will not pass up the opportunity to snack on a few guppy fry. It will occasionally hide among the plants and sneak out at snatch an unsuspecting fry, however there are still many fry in the tank after several months and it seems to only eat the youngest ones (less than about two weeks old). It may be beneficial then to house this difficult feeder with at least one female guppy in the presence of a male so that a food source will always be available. For this same reason, it may be wise to avoid shrimp as tankmates as they will likely become a meal.
i have 5 of the spread out in 3 different tanks... awesome little fish, amazing colors. very peaceful. although they prefer live or frozen food... i had little trouble getting them to eat spectrum pellets and flake. (won't eat is from top but it you take a pinch and release underwater so it floats towards bottom they gobble it up)
i must be doing something right mine r the other way round i have couple of hundred of these little critters fry(from one pr)they will only eat freeze dried foods and flake just gave first brood to my lfs because he gave me the adults in first place. does anyone know any thing about the other gobies i have just got black toraja goby fetched one pr last wednesday and another pr from differant lfs on saturday now both spawned and fanning away in tubes need to know incubation and feeding habits hope someone can help or point me in right direction thanx for reading
i currently have a pair. and i love these fish, super colorful an full of personality. i currently have mine housed with a CPO, and many Red Cherry Shrimp. unlike the person above has said (for me atleast) they do not eat my shrimp, and RCS colony is growning in the tank. mine will eat nearly any frozen food i put in the tank, from blood and glassworms to BrineShrimp, and emerald entree. They also really love crushed snail. i have a snail problem in my shrimp tank, so the ones i catch i crush and give to my gudgeons. when they are young it is difficult sex them, but the males mature quickly and it become very obvious who is what. I am still trying get fry to survive.
I was trying to hurry up and start my account so I could jump in here! My male peacock gudgeon was aggressively attacking my female, I was afraid he would injure her. They made a nest in a hole in my lace rock when I first dropped them in my tank, but I didn't get the eggs out in time and someone had a good meal lol... Anyway, I was ready to separate them when suddenly the female was following the male around and he wasn't attacking her. He led her back to the same hole in the rock and they did the deed lol... I guess that's what all the aggression was about...? Hopefully I can grab the male and the eggs this time and throw them in my breeding tank. These fish are gorgeous and fearless, making them a beautiful species for community tanks! I haven't had issues with feeding them. I switch off between hikari bloodworms and sinking spirulina wafers, and they enjoy both. I keep them in a planted 15g tall with pygmy Corys, Amano shrimp, and Danio Erythromicron. Their boldness makes the danios brave enough to come out from the plants more often.
These fish are awesome. I keep a breeding pair in a 10 gallon planted with red cherry shrimp. They may pick off some shrimplets but I have got to see them do it. They never mess with the adult shrimp. My pair will eat anything including freeze dried and frozen foods. Since I added the female they have spawned three times (like every two weeks) and I am currently raising 40 or so fry. It helps to let the male fan the eggs until they're ready to hatch and then remove them to a breeding/grow out tank. What a lovely fish.
