Overstocked, Stocked Or Understocked?

[QuotheRaven]

75 Gallon: Eheim Classic Cannister Filter, Jager 300 watt Heater, Sand Bottom
Fully Cycled
1 x Neosilurus rendahli
2 x Angelfish
2 x Platies
1 x Bristlenose Catfish
2 x Yoyo Loaches
1 x Swordtail
2 x Tiger Barbs
5 x Harlequin Rasbora's
1 x Golden Severum
1 x Botia Sidthimunki

now just say that everyone of those fish is fully grown ( rendahli is 30cm in the wild but it rarely exceeds 20 cm in home aquariums)

Now it is also worth mentioning that the swordtail, platies, Monkey Botia & the rasbora's will be moved with the addition of 2 kribensis so projected stock.

what does everyone think??
If understocked what would go with those fish & how many more fish could fit into the tank if understocked.

Im no expert but shouldnt you have at least 5 or 6 Tiger Barbs together, thats what I have always been told.

I agree. Apparently Tiger Barbs can be quite aggressive to other fish unless they are kept in a group.

I would advise having at least 8 tiger barbs, the more you have the less agressive they are likely to be, either towards each other or other fish.
The 75gallon has stocking issues mostly due to the types of fish you have rather than bioload issues, wether fish you currently have or want to have. Livebearers like platys, guppys and mollys need to have at least 2-3 females per male, and with swordtails you should only have one male tops but at least 2-3 females (male swordtails fight each other a lot regardless of how many females you have unless its an exceptional amount i.e. minimum of 15 females to each male).
Yoyo loaches a.k.a pakistani loaches do best in groups 4-5+.
I'm no expert on severums, but i would have thought they would be too agressive for your tank?
Be wary of angelfish, they can become very agressive towards other fish when they pair up for mating/breeding, and its not uncommon for them to do so at that.

I think severums are described as gentle giants? I dunno myself

 

[QuotheRaven]

My tiger barbs are probably the least aggressive fish in my tank they have NEVER attacked my other fish.

The two platies are female & the swordtail is a male.

I am going to purchase some more yoyo's soon.

My severum is aggressive towards fish smaller than him at feeding time and occasionally snaps at the angels but thats it.

anyone have anymore comments???
I am really after if it's overstocked or not ( the fish in the tank appear happy healthy and there is no behavioural problems)

 

[QuotheRaven]

anyone got anything else to add

Tokis-Phoenix has it right - from a pure bioload standpoint, you're not overstocked, not really close even.

Based on the mix of fish, I would say it was only a matter of time before it became the Highlander Tank - there can be only one. 3-4 more yoyos and 4-6 more tiger barbs may keep you from having neurotic fish in the long run, but your mileage may vary, nu?

 

[QuotheRaven]

well I am getting more yoyo's probably tommorow however I am not risking more Tbs as I never bought the tbs in the first place they were a gift and I have lucked out on some peaceful tbs and I don't want to risk getting nasty Tiger barbs. They are happy and active.

So Im not even close to being overstocked??

Sorry, spoke without thought. Honestly, I am not 100% sure. At a glance, though, I think you're just fine on the bioload. Add more fish slowly and carefully.

I have a quarentine tank for new arrivals & a 32 gallon for to many fish....

Then you'll be fine.
