Can I add any of these fish to my tank?

What Other Freshwater Aggressive/Semi-Aggressive fish can i add to my fish tank?

  • Hey all, so i have a 40 gallon fish tank that i have been taking care of for almost 2 years now. When i first received the tank i went straight into community fish, as time has progressed and some of the smaller community fish have died i have slowly added Semi-agressive fish to my tank. At the Present moment this is a list of what occupies my 40 gallon tank... 1. one 7inch Blue Lobster 2. one 8 inch Leopard Plecostomus 3. one 6 inch Black Upside down Catfish 4. one 6 inch Clown Loach 5. one 4 inch Red Crayfish 6. two 8 inch Rope-fish 7. one 6 inch Alligator Garr 8. one 6 inch Shovel Nose Catfish This group of 8 are the big boys/girls in my tank, especially the Pleco and the Lobster. The Rope-fish are Male and female and have a separate tank ready to go in case of breeding. The group has lasted 3 weeks now without much conflict other then a few tail clippings here and there but otherwise everyone is eating well... i just wanted to know if i can be doing something more to help make my fish happy living together, i also just recently gave my mother 3 of my tetra fish so they were not eaten by my Garr or shovel nose... i do still have two Silver Dollar Tetras in my tank that seem to be doing fine for now but they will probably soon be given away as well just for safety issues. FYI i also have another 20gallon tank, But this one already has one betta Female a small Freshwater Flounder and 2 small butterfly Koi From our outside pond that we bring in during the winter. id love to hear any suggestions or comments from anyone who cares to give them. Thanks Everyone!! - S

    Agreed. That is an ABSURD stocking for any tank less than 500 gallons. Please do some research into the basic requirements of your fish, including minimum volume requirements, compatibility, and grouping needs. Then, assuming you're not in the market for a 500+ gallon setup, return them ALL except maybe the Upside Down Catfish, and refrain from purchasing further stock for whom you have not properly prepared.

And a/some Koi in a 20 gallon?!?!?? Who sells you these fish? I can't even believe PetSmart and the like would condone this sort of nonsense.

EPIC FAIL TANK. RETURN THEM ALL AND NEVER KEEP FISH AGAIN.

I'm afraid there are just too many ill-researched additions to your 40g to consider adding anything else. The Shovelnose needs out. So does the Gar. These guys are called "tank busters" for a reason. You need more like over 400 gallons, not 40 gallons, to keep those guys contented. The Shovelnose especially is probably eyeing up those Crays for dinner too. The Red Cray, if its the species I think it is, needs a cool water species tank. The Blue Cray needs a tropical species tank. They really do better in their own tanks, alone! You need to rehome some fish. Do species research. The size a fish is when you buy it is completely irrelevant. Fish, like that Shovelnose, grow FAST. EDIT: You need to visit http://www.monsterfishkeepers.com They keep Shovelnoses in 500g+ ponds. Koi need ponds over 1,500 gallons too. While 150g sounds big, when it comes to keeping big fish it suddenly becomes very small!! Clown Loaches alone shouldn't be kept, they need shoals of 6+. Adults of these guys need a tank at least 6ft long. Shopping at pet supermarkets is always a poor idea (and if I had my way no mainstream store would stock fish that grow over 6" unless specifically specially ordered - in fact my local aquatic shop does this and has several 5ft tanks and a 10ft long show tank to take in overgrown rescues! Always at least 6-10 large "common" and sailfin Plecos over 12" in there which have been dumped on them.) OH and that Cray may make a meal of the Koi.

It's like building a tank stocking list based on the Highlander series - "In The End, There Can Be Only One." If what you truly have is an Alligator Gar - not a Needlenose - those puppies can grow 6-8 FEET long and need practically their own river to swim in. 1. one 7inch Blue Lobster - Dinner 2. one 8 inch Leopard Plecostomus - Dinner 3. one 6 inch Black Upside down Catfish - Dinner 4. one 6 inch Clown Loach - Dinner 5. one 4 inch Red Crayfish - Dinner 6. two 8 inch Rope-fish - Dinner 7. one 6 inch Alligator Gar - Fat and Happy 8. one 6 inch Shovel Nose Catfish - Dinner You could keep the shovelnose in the 150g tank you're eyeing until he reaches about 15"-18" in length, then you'll have to rehome him. In the meantime, get rid of everything else. Then stock the tank that has the shovelnose with a few - like, 3 - large oscars. Also, shovelnose catfish are high octane fish, plan on about TWICE the recommended filtration for your tank if you are feeding him properly.
