First of all, the goldfish is far too big for a 10 gallons tank. A pair is better off in a 40 gallons tank. You need to buy a biggest tank you can afford as soon as possible.
I assume the algae eaters are the Chinese Algae Eaters. Scientific name is in "Freshwater Species" section. It's posted in the Cyprinids thread for reference. For quick info, pls avoid them. They grow to 25 cm, can suck the other fish's mucous membrane and even eat smaller fish. While juveniles can eat algae, they'll lose the taste for algae as they mature. This is the stage where they develop a taste for mucous membranes which can severely damage your other fish.
Is the African Dwarf Frog a clawed one? Avoid them as they can be predatory.
What kind of filter do yo use? The brand name? Some filters are of good quality but some can be bad.
so, about a month ago one of our goldfish strated to go crazy!! he swam really fast and was all over the place. so he started to bump into other fish and into the glass, but THEN he strated to jump and bumped into the light up above. we started to get worried. it lasted for about 2, 2 1/2 weeks. he would hit himself do hard that he would "pass out" for a little bit and then continue his crazy rampide.... |
well, then he died.... but now our concern is that now ALL of the other fish started to act out, and there is one that grows by the minute, so if he swims too fast we WILL end up killing himself!!
Pls consider buying a test kit. You need to test the pH, GH(General Hardness), KH(Carbonate Hardness), ammonia, nitrites and nitrates. Post the exact figures. API Master Test Kit is your best option.
also the last time we cleaned the tank (after the death) we found these small insects in one of the filters, they were REALLY small they jumped or flew dunno... they were in only on one of the filters. someone told me that they looked like "fruit flies"???
I doubt that would be fruit flies. How do you clean your tank? Do you clean them by starting from scratch? If so, it's a no-no. You are repeating the nitrogen cycle again and again. Ammonia produced by fish wastes is converted by bacteria into nitrites, then finally into nitrates which is the most harmless of the three.
Clean your filter media(floss, foam, etc) using the tank water everytime you do a water change. Avoid using hot water and detergents.
Do a water change for 3 times a week. When I say water change, you vacuum the gravel with a siphon and change the water with a new treated water. Treat your tapwater with dechlorinator to eliminate chlorine, chloramine and other heavy metals. Those are very dangerous to the fish.
Another rule: Never mix tropical fish with coldwater fish.
Chinese Algae Eater=tropical fish
They won't thrive together due to different requirements especially when temp is concerned.
Pls post as many questions as you can so you can sort everything well.
