just to let you know,
the RTB will get to 5-7"
the clown loaches wil get to almost 2 feet long each
the siameese figher (betta) will be ok by themselfs, they like to be solitary fish.
for the most part all your fish are incompatable and most need rehoming.
i like you dude i really do, but you come up with some funny stats sometimes
2 feet long Clown Loach?
i think thats pushing it mate
possibly in "theory" somewhere.....
EDIT: in "fairness" you said "almost 2 foot" and i think 14-16" has been achieved in aquaria, possibly more, but i do laugh sometimes on this forum when i see people throwing these wild stats about, and telling people they need a this and that gallon tank for something like fish keeping is some magic formula where you if get the right gallon tank you are sorted (slight exageration perhaps and i know for sure a 35 litre is way to small, WAY too small), no disrespect, this persons set up is problematic big time and they need advice, but do we have to go throwing numbers about so randomly?
So someone is telling the poster Clown Loach "need" a 90 gallon tank? I think we need to be careful with these figures, the poster could go away thinking he cant keep Clowns unless he had a 90 gallon tank, thats simply not true, he CERTAINLY needs a bigger thank for sure.
I think we should just add some substance to when we quote this statistics and numbers at peeps, especially newbie types.
The guy who quoted Clowns "need" 90 gallons lives in UK, so that means 410 litres.
So if i had a 48x20x20 tank which is 66 UK Gallons and 300 litres i cant keep Clown Loach?
I think the guy that said that is RESPONSIBLE and in someway perhaps correct, but lets just put things into perspective, a Clown Loach is a slow growing fish, and if you have a reasonable size tank and provide good water quality and feeding, there is a lot more than "size of tank", DISCLAIMER: within reason, my view is that Clown Loach should be kept in groups of x4 minimum and that your tank should be atleast 40" and pref 48" long and atleast 200 litres, pref a bit more (i.e 45 UK gallons minimum and 54 US Gallons)
EDIT: my Clown Loach figures are bare minimum
EDIT: no disprespect to afishdude who knows a lot from his other posts
